   * **expressive** - As JSONSelect evolves, it will include more of the most popular constructs from the CSS spec and popular implementations (like [sizzle](http://sizzlejs.com/)).  A successful result will be a good balance of simplicity and power.

   * **incremental adoption** - JSONSelect features are broken in to conformance levels, to make it easier to build basic support and to allow incremental stabilization of the language.

+ JSHINT is a global function. It takes two parameters.
+
+     var myResult = JSHINT(source, option);
+
+ The first parameter is either a string or an array of strings. If it is a
+ string, it will be split on '\n' or '\r'. If it is an array of strings, it
+ is assumed that each string represents one line. The source can be a
+ JavaScript text or a JSON text.
+
+ The second parameter is an optional object of options which control the
+ operation of JSHINT. Most of the options are booleans: They are all
+ optional and have a default value of false. One of the options, predef,
+ can be an array of names, which will be used to declare global variables,
+ or an object whose keys are used as global names, with a boolean value
+ that determines if they are assignable.
+
+ If it checks out, JSHINT returns true. Otherwise, it returns false.
+
+ If false, you can inspect JSHINT.errors to find out the problems.
+ JSHINT.errors is an array of objects containing these members:
+
+ {
+     line      : The line (relative to 0) at which the lint was found
+     character : The character (relative to 0) at which the lint was found
+     reason    : The problem
+     evidence  : The text line in which the problem occurred
+     raw       : The raw message before the details were inserted
+     a         : The first detail
+     b         : The second detail
+     c         : The third detail
+     d         : The fourth detail
+ }
+
+ If a fatal error was found, a null will be the last element of the
+ JSHINT.errors array.
+
+ You can request a Function Report, which shows all of the functions
+ and the parameters and vars that they use. This can be used to find
+ implied global variables and other problems. The report is in HTML and
+ can be inserted in an HTML .
+
+     var myReport = JSHINT.report(limited);
+
+ If limited is true, then the report will be limited to only errors.
+
+ You can request a data structure which contains JSHint's results.
+
+     var myData = JSHINT.data();
+
+ It returns a structure with this form:
+
+ {
+     errors: [
+         {
+             line: NUMBER,
+             character: NUMBER,

+    JSLINT is a global function. It takes two parameters.
+
+        var myResult = JSLINT(source, option);
+
+    The first parameter is either a string or an array of strings. If it is a
+    string, it will be split on '\n' or '\r'. If it is an array of strings, it
+    is assumed that each string represents one line. The source can be a
+    JavaScript text, or HTML text, or a Konfabulator text.
+
+    The second parameter is an optional object of options which control the
+    operation of JSLINT. Most of the options are booleans: They are all are
+    optional and have a default value of false.
+
+    If it checks out, JSLINT returns true. Otherwise, it returns false.
+
+    If false, you can inspect JSLINT.errors to find out the problems.
+    JSLINT.errors is an array of objects containing these members:
+
+    {
+        line      : The line (relative to 0) at which the lint was found
+        character : The character (relative to 0) at which the lint was found
+        reason    : The problem
+        evidence  : The text line in which the problem occurred
+        raw       : The raw message before the details were inserted
+        a         : The first detail
+        b         : The second detail
+        c         : The third detail
+        d         : The fourth detail
+    }
+
+    If a fatal error was found, a null will be the last element of the
+    JSLINT.errors array.
+
+    You can request a Function Report, which shows all of the functions
+    and the parameters and vars that they use. This can be used to find
+    implied global variables and other problems. The report is in HTML and
+    can be inserted in an HTML .
+
+        var myReport = JSLINT.report(limited);
+
+    If limited is true, then the report will be limited to only errors.
+
+    You can request a data structure which contains JSLint's results.
+
+        var myData = JSLINT.data();
+
+    It returns a structure with this form:
+
+    {
+        errors: [

+/***********************************************************************
+
+  A JavaScript tokenizer / parser / beautifier / compressor.
+
+  This version is suitable for Node.js.  With minimal changes (the
+  exports stuff) it should work on any JS platform.
+
+  This file contains the tokenizer/parser.  It is a port to JavaScript
+  of parse-js [1], a JavaScript parser library written in Common Lisp
+  by Marijn Haverbeke.  Thank you Marijn!
+
+  [1] http://marijn.haverbeke.nl/parse-js/
+
+  Exported functions:
+
+    - tokenizer(code) -- returns a function.  Call the returned
+      function to fetch the next token.
+
+    - parse(code) -- returns an AST of the given JavaScript code.

+/***********************************************************************
+
+  A JavaScript tokenizer / parser / beautifier / compressor.
+
+  This version is suitable for Node.js.  With minimal changes (the
+  exports stuff) it should work on any JS platform.
+
+  This file implements some AST processors.  They work on data built
+  by parse-js.
+
+  Exported functions:
+
+    - ast_mangle(ast, options) -- mangles the variable/function names
+      in the AST.  Returns an AST.
+
+    - ast_squeeze(ast) -- employs various optimizations to make the
+      final generated code even smaller.  Returns an AST.
+
+    - gen_code(ast, options) -- generates JS code from the AST.  Pass
+      true (or an object, see the code for some options) as second
+      argument to get "pretty" (indented) code.

+
+
+    This file creates a global JSON object containing two methods: stringify
+    and parse.
+
+        JSON.stringify(value, replacer, space)
+            value       any JavaScript value, usually an object or array.
+
+            replacer    an optional parameter that determines how object
+                        values are stringified for objects. It can be a
+                        function or an array of strings.
+
+            space       an optional parameter that specifies the indentation
+                        of nested structures. If it is omitted, the text will
+                        be packed without extra whitespace. If it is a number,
+                        it will specify the number of spaces to indent at each
+                        level. If it is a string (such as '\t' or ' '),
+                        it contains the characters used to indent at each level.
+
+            This method produces a JSON text from a JavaScript value.
+
+            When an object value is found, if the object contains a toJSON
+            method, its toJSON method will be called and the result will be
+            stringified. A toJSON method does not serialize: it returns the
+            value represented by the name/value pair that should be serialized,
+            or undefined if nothing should be serialized. The toJSON method
+            will be passed the key associated with the value, and this will be
+            bound to the value
+
+            For example, this would serialize Dates as ISO strings.
+
+                Date.prototype.toJSON = function (key) {
+                    function f(n) {
+                        // Format integers to have at least two digits.
+                        return n < 10 ? '0' + n : n;
+                    }
+
+                    return this.getUTCFullYear()   + '-' +
+                         f(this.getUTCMonth() + 1) + '-' +
+                         f(this.getUTCDate())      + 'T' +
+                         f(this.getUTCHours())     + ':' +
+                         f(this.getUTCMinutes())   + ':' +
+                         f(this.getUTCSeconds())   + 'Z';
+                };
+
+            You can provide an optional replacer method. It will be passed the
+            key and value of each member, with this bound to the containing
+            object. The value that is returned from your method will be
+            serialized. If your method returns undefined, then the member will
+            be excluded from the serialization.
+
+            If the replacer parameter is an array of strings, then it will be
+            used to select the members to be serialized. It filters the results
+            such that only members with keys listed in the replacer array are
+            stringified.
+
+            Values that do not have JSON representations, such as undefined or
+            functions, will not be serialized. Such values in objects will be
+            dropped; in arrays they will be replaced with null. You can use
+            a replacer function to replace those with JSON values.
+            JSON.stringify(undefined) returns undefined.
+
+            The optional space parameter produces a stringification of the
+            value that is filled with line breaks and indentation to make it
+            easier to read.
+
+            If the space parameter is a non-empty string, then that string will
+            be used for indentation. If the space parameter is a number, then
+            the indentation will be that many spaces.
+
+            Example:
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}]);
+            // text is '["e",{"pluribus":"unum"}]'
+
+
+            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
+            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
+
+            text = JSON.stringify([new Date()], function (key, value) {
+                return this[key] instanceof Date ?
+                    'Date(' + this[key] + ')' : value;
+            });
+            // text is '["Date(---current time---)"]'
+
+
+        JSON.parse(text, reviver)
+            This method parses a JSON text to produce an object or array.
+            It can throw a SyntaxError exception.
+
+            The optional reviver parameter is a function that can filter and
+            transform the results. It receives each of the keys and values,
+            and its return value is used instead of the original value.
+            If it returns what it received, then the structure is not modified.
+            If it returns undefined then the member is deleted.
+
+            Example:
+
+            // Parse the text. Values that look like ISO date strings will
+            // be converted to Date objects.
+
+            myData = JSON.parse(text, function (key, value) {
+                var a;
+                if (typeof value === 'string') {
+                    a =
+/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
+                    if (a) {
+                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+                            +a[5], +a[6]));
+                    }
+                }
+                return value;
+            });
+
+            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
+                var d;
+                if (typeof value === 'string' &&
+                        value.slice(0, 5) === 'Date(' &&
+                        value.slice(-1) === ')') {
+                    d = new Date(value.slice(5, -1));
+                    if (d) {

+
+// We split the second stage into 4 regexp operations in order to work around
+// crippling inefficiencies in IE's and Safari's regexp engines. First we
+// replace the JSON backslash pairs with '@' (a non-JSON character). Second, we
+// replace all simple value tokens with ']' characters. Third, we delete all
+// open brackets that follow a colon or comma or that begin the text. Finally,

+// ',' or ':' or '{' or '}'. If that is so, then the text is safe for eval.

+// in JavaScript: it can begin a block or an object literal. We wrap the text
+// in parens to eliminate the ambiguity.
+
+                j = eval('(' + text + ')');
+
