 This package provides an <em>object-model neutral</em> API for the
 evaluation of XPath expressions and access to the evaluation
 environment.
 <p>
 The XPath API supports <a href="http://www.w3.org/TR/xpath">
 XML Path Language (XPath) Version 1.0</a>

 <h3>1. XPath Overview</h3>
 <p>The XPath language provides a simple, concise syntax for selecting
 nodes from an XML document. XPath also provides rules for converting a
 node in an XML document object model (DOM) tree to a boolean, double,
 XPointer languages, but has more recently become popular as a
 stand-alone language, as a single XPath expression can be used to
 replace many lines of DOM API code.
 </p>

+<a id="XPath.Expressions"></a>
 <h3>2. XPath Expressions</h3>
 <p>An XPath <em>expression</em> is composed of a <em>location
 path</em> and one or more optional <em>predicates</em>. Expressions
 may also include XPath variables.
 <p>In addition to element nodes, XPath location paths may also address
 attribute nodes, text nodes, comment nodes, and processing instruction
 nodes. The following table gives examples of location paths for each
 of these node types:</p>
-<table border="1">
+<table class="striped">
-<tr>
+<caption>Examples of Location Path</caption>
-<td>Location Path</td>
+<thead>
-<td>Description</td>
+<tr>
-</tr>
+<th>Location Path</th>
+<th>Description</th>
+</tr>
+</thead>
+<tbody>
 <tr>
 <td>
 <code>/foo/bar/<strong>@id</strong></code>
 </td>
 <td>Selects the attribute <code>id</code> of the <code>&lt;bar&gt;</code> element
 </td>
 <td>Selects all processing-instruction nodes contained in the
 <code>&lt;bar&gt;</code> element.
 </td>
 </tr>
+</tbody>
 </table>
 <p>Predicates allow for refining the nodes selected by an XPath
 location path. Predicates are of the form
 <code>[<em>expression</em>]</code>. The following example selects all
 <pre>
 //foo[@include='true'][@mode='bar']
 </pre>

 <h3>3. XPath Data Types</h3>
 <p>While XPath expressions select nodes in the XML document, the XPath
 API allows the selected nodes to be coalesced into one of the
 following data types:</p>
 <li><code>Boolean</code></li>
 <li><code>Number</code></li>
 <li><code>String</code></li>
 </ul>
-<a name="XPath.Datatypes.QName"></a>
+<a id="XPath.Datatypes.QName"></a>
 <h3>3.1 QName types</h3>
 The XPath API defines the following {@link javax.xml.namespace.QName} types to
 represent return types of an XPath evaluation:
 <ul>
 <li>{@link javax.xml.xpath.XPathConstants#NODESET}</li>
 of the child text nodes is returned.
 <p>The <code>Number</code> return type attempts to coalesce the text
 of a node to a <code>double</code> data type.
-<a name="XPath.Datatypes.Class"></a>
+<a id="XPath.Datatypes.Class"></a>
 <h3>3.2 Class types</h3>
 In addition to the QName types, the XPath API supports the use of Class types
 through the <code>XPathExpression.evaluteExpression(...)</code> or
 <code>XPath.evaluateExpression(...)</code> methods.
 </ul>
 <p>
 Of the subtypes of Number, only Double, Integer and Long are supported.
-<a name="XPath.Datatypes.Enum"></a>
+<a id="XPath.Datatypes.Enum"></a>
 <h3>3.3 Enum types</h3>
 Enum types are defined in {@link javax.xml.xpath.XPathEvaluationResult.XPathResultType}
 that provide mappings between the QName and Class types above. The result of
 evaluating an expression using the <code>XPathExpression.evaluteExpression(...)</code>
 or <code>XPath.evaluateExpression(...)</code> methods will be of one of these types.
-<a name="XPath.Context"></a>
+<a id="XPath.Context"></a>
 <h3>4. XPath Context</h3>
 <p>XPath location paths may be relative to a particular node in the
 document, known as the <code>context</code>. A context consists of:
 <ul>
 <p>
 It is an XML document tree represented as a hierarchy of nodes, a
 {@link org.w3c.dom.Node} for example, in the JDK implementation.
