+	/**
+	 * Defines an object that runs Selenium commands.
+	 * 
+	 * <h3><a name="locators"></a>Element Locators</h3>
+	 * <p>
+	 * Element Locators tell Selenium which HTML element a command refers to.
+	 * The format of a locator is:</p>
+	 * <blockquote>
+	 * <em>locatorType</em><strong>=</strong><em>argument</em>
+	 * </blockquote>
+	 * 
+	 * <p>
+	 * We support the following strategies for locating elements:
+	 * </p>
+	 * <blockquote>
+	 * <dl>
+	 * <dt><strong>identifier</strong>=<em>id</em></dt>
+	 * <dd>Select the element with the specified &#64;id attribute. If no match is
+	 * found, select the first element whose &#64;name attribute is <em>id</em>.
+	 * (This is normally the default; see below.)</dd>
+	 * <dt><strong>id</strong>=<em>id</em></dt>
+	 * <dd>Select the element with the specified &#64;id attribute.</dd>
+	 * 
+	 * <dt><strong>name</strong>=<em>name</em></dt>
+	 * <dd>Select the first element with the specified &#64;name attribute.</dd>
+	 * <dd><ul class="first last simple">
+	 * <li>username</li>
+	 * <li>name=username</li>
+	 * </ul>
+	 * </dd>
+	 * <dd>The name may optionally be followed by one or more <em>element-filters</em>, separated from the name by whitespace.  If the <em>filterType</em> is not specified, <strong>value</strong> is assumed.</dd>
+	 * 
+	 * <dd><ul class="first last simple">
+	 * <li>name=flavour value=chocolate</li>
+	 * </ul>
+	 * </dd>
+	 * <dt><strong>dom</strong>=<em>javascriptExpression</em></dt>
+	 * 
+	 * <dd>
+	 * 
+	 * <dd>Find an element using JavaScript traversal of the HTML Document Object
+	 * Model. DOM locators <em>must</em> begin with &quot;document.&quot;.
+	 * <ul class="first last simple">
+	 * <li>dom=document.forms['myForm'].myDropdown</li>
+	 * <li>dom=document.images[56]</li>
+	 * </ul>
+	 * </dd>
+	 * 
+	 * </dd>
+	 * 
+	 * <dt><strong>xpath</strong>=<em>xpathExpression</em></dt>
+	 * <dd>Locate an element using an XPath expression.
+	 * <ul class="first last simple">
+	 * <li>xpath=//img[&#64;alt='The image alt text']</li>
+	 * <li>xpath=//table[&#64;id='table1']//tr[4]/td[2]</li>
+	 * 
+	 * </ul>
+	 * </dd>
+	 * <dt><strong>link</strong>=<em>textPattern</em></dt>
+	 * <dd>Select the link (anchor) element which contains text matching the
+	 * specified <em>pattern</em>.
+	 * <ul class="first last simple">
+	 * <li>link=The link text</li>
+	 * </ul>
+	 * 
+	 * </dd>
+	 * </dl>
+	 * </blockquote>
+	 * <p>
+	 * Without an explicit locator prefix, Selenium uses the following default
+	 * strategies:
+	 * </p>
+	 * 
+	 * <ul class="simple">
+	 * <li><strong>dom</strong>, for locators starting with &quot;document.&quot;</li>
+	 * <li><strong>xpath</strong>, for locators starting with &quot;//&quot;</li>
+	 * <li><strong>identifier</strong>, otherwise</li>
+	 * </ul>
+	 *
+	 * <h3><a name="element-filters">Element Filters</a></h3>
+	 * <blockquote>
+	 * <p>Element filters can be used with a locator to refine a list of candidate elements.  They are currently used only in the 'name' element-locator.</p>
+	 * <p>Filters look much like locators, ie.</p>
+	 * <blockquote>
+	 * <em>filterType</em><strong>=</strong><em>argument</em></blockquote>
+	 * 
+	 * <p>Supported element-filters are:</p>
+	 * <p><strong>value=</strong><em>valuePattern</em></p>
+	 * <blockquote>
+	 * Matches elements based on their values.  This is particularly useful for refining a list of similarly-named toggle-buttons.</blockquote>
+	 * <p><strong>index=</strong><em>index</em></p>
+	 * <blockquote>
+	 * Selects a single element based on its position in the list (offset from zero).</blockquote>
+	 * </blockquote>
+	 *
+	 * <h3><a name="patterns"></a>String-match Patterns</h3>
+	 * 
+	 * <p>
+	 * Various Pattern syntaxes are available for matching string values:
+	 * </p>
+	 * <blockquote>
+	 * <dl>
+	 * <dt><strong>glob:</strong><em>pattern</em></dt>
+	 * <dd>Match a string against a "glob" (aka "wildmat") pattern. "Glob" is a
+	 * kind of limited regular-expression syntax typically used in command-line
+	 * shells. In a glob pattern, "*" represents any sequence of characters, and "?"
+	 * represents any single character. Glob patterns match against the entire
+	 * string.</dd>
+	 * <dt><strong>regexp:</strong><em>regexp</em></dt>
+	 * <dd>Match a string using a regular-expression. The full power of JavaScript
+	 * regular-expressions is available.</dd>
+	 * <dt><strong>exact:</strong><em>string</em></dt>
+	 * 
+	 * <dd>Match a string exactly, verbatim, without any of that fancy wildcard
+	 * stuff.</dd>
+	 * </dl>
+	 * </blockquote>
+	 * <p>
+	 * If no pattern prefix is specified, Selenium assumes that it's a "glob"
+	 * pattern.

+// The API of the parser has several parts:
+//
+// 1. The parser function xpathParse() that takes a string and returns
+// an expession object.
+//
+// 2. The expression object that has an evaluate() method to evaluate the
+// XPath expression it represents. (It is actually a hierarchy of
+// objects that resembles the parse tree, but an application will call
+// evaluate() only on the top node of this hierarchy.)
+//
+// 3. The context object that is passed as an argument to the evaluate()
+// method, which represents the DOM context in which the expression is
+// evaluated.
+//
+// 4. The value object that is returned from evaluate() and represents
+// values of the different types that are defined by XPath (number,
+// string, boolean, and node-set), and allows to convert between them.
+//
+// These parts are near the top of the file, the functions and data

+//
+// The interface of the expression context:

+//   belongs to, and a parent context as arguments. The parent context
+//   is used to implement scoping rules for variables: if a variable
+//   is not found in the current context, it is looked for in the
+//   parent context, recursively. Except for node, all arguments have
+//   default values: default position is 0, default node set is the
+//   set that contains only the node, and the default parent is null.
+//
+//     Notice that position starts at 0 at the outside interface;
+//     inside XPath expressions this shows up as position()=1.
+//
+//   clone() -- creates a new context with the current context as
+//   parent. If passed as argument to clone(), the new context has a
+//   different node, position, or node set. What is not passed is
+//   inherited from the cloned context.
+//
+//   setVariable(name, expr) -- binds given XPath expression to the
+//   name.
