/**
16 
 *  The <code>TypeInfo</code> interface represents a type referenced from
17 
 * <code>Element</code> or <code>Attr</code> nodes, specified in the schemas
18 
 * associated with the document. The type is a pair of a namespace URI and
19 
 * name properties, and depends on the document's schema.
20 
 * <p> If the document's schema is an XML DTD [<a href='http://www.w3.org/TR/2004/REC-xml-20040204'>XML 1.0</a>], the values
21 
 * are computed as follows:
22 
 * <ul>
23 
 * <li> If this type is referenced from an
24 
 * <code>Attr</code> node, <code>typeNamespace</code> is
25 
 * <code>"http://www.w3.org/TR/REC-xml"</code> and <code>typeName</code>
26 
 * represents the <b>[attribute type]</b> property in the [<a href='http://www.w3.org/TR/2004/REC-xml-infoset-20040204/'>XML Information Set</a>]
27 
 * . If there is no declaration for the attribute, <code>typeNamespace</code>
28 
 *  and <code>typeName</code> are <code>null</code>.
29 
 * </li>
30 
 * <li> If this type is
31 
 * referenced from an <code>Element</code> node, <code>typeNamespace</code>
32 
 * and <code>typeName</code> are <code>null</code>.
33 
 * </li>
34 
 * </ul>
35 
 * <p> If the document's schema is an XML Schema [<a href='http://www.w3.org/TR/2001/REC-xmlschema-1-20010502/'>XML Schema Part 1</a>]
36 
 * , the values are computed as follows using the post-schema-validation
37 
 * infoset contributions (also called PSVI contributions):
38 
 * <ul>
39 
 * <li> If the <b>[validity]</b> property exists AND is <em>"invalid"</em> or <em>"notKnown"</em>: the {target namespace} and {name} properties of the declared type if
40 
 * available, otherwise <code>null</code>.
41 
 * <p ><b>Note:</b>  At the time of writing, the XML Schema specification does
42 
 * not require exposing the declared type. Thus, DOM implementations might
43 
 * choose not to provide type information if validity is not valid.
44 
 * </li>
45 
 * <li> If the <b>[validity]</b> property exists and is <em>"valid"</em>:
46 
 * <ol>
47 
 * <li> If <b>[member type definition]</b> exists:
48 
 * <ol>
49 
 * <li>If {name} is not absent, then expose {name} and {target
50 
 * namespace} properties of the <b>[member type definition]</b> property;
51 
 * </li>
52 
 * <li>Otherwise, expose the namespace and local name of the
53 
 * corresponding anonymous type name.
54 
 * </li>
55 
 * </ol>
56 
 * </li>
57 
 * <li> If the <b>[type definition]</b> property exists:
58 
 * <ol>
59 
 * <li>If {name} is not absent, then expose {name} and {target
60 
 * namespace} properties of the <b>[type definition]</b> property;
61 
 * </li>
62 
 * <li>Otherwise, expose the namespace and local name of the
63 
 * corresponding anonymous type name.
64 
 * </li>
65 
 * </ol>
66 
 * </li>
67 
 * <li> If the <b>[member type definition anonymous]</b> exists:
68 
 * <ol>
69 
 * <li>If it is false, then expose <b>[member type definition name]</b> and <b>[member type definition namespace]</b> properties;
70 
 * </li>
71 
 * <li>Otherwise, expose the namespace and local name of the
72 
 * corresponding anonymous type name.
73 
 * </li>
74 
 * </ol>
75 
 * </li>
76 
 * <li> If the <b>[type definition anonymous]</b> exists:
77 
 * <ol>
78 
 * <li>If it is false, then expose <b>[type definition name]</b> and <b>[type definition namespace]</b> properties;
79 
 * </li>
80 
 * <li>Otherwise, expose the namespace and local name of the
81 
 * corresponding anonymous type name.
