25		*
26		* <p>This class encapsulates the logic of Namespace processing: it
27		* tracks the declarations currently in force for each context and
28		* automatically processes qualified XML names into their Namespace
29		* parts; it can also be used in reverse for generating XML qnames
30		* from Namespaces.</p>
31		*
32		* <p>Namespace support objects are reusable, but the reset method
33		* must be invoked between each session.</p>
34		*
35		* <p>Here is a simple session:</p>
36		*
37		* <pre>
38		* String parts[] = new String[3];
39		* NamespaceSupport support = new NamespaceSupport();
40		*
41		* support.pushContext();
42		* support.declarePrefix("", "http://www.w3.org/1999/xhtml");
43		* support.declarePrefix("dc", "http://www.purl.org/dc#");
44		*
45		* parts = support.processName("p", parts, false);
46		* System.out.println("Namespace URI: " + parts[0]);
47		* System.out.println("Local name: " + parts[1]);
48		* System.out.println("Raw name: " + parts[2]);
49		*
50		* parts = support.processName("dc:title", parts, false);
51		* System.out.println("Namespace URI: " + parts[0]);
52		* System.out.println("Local name: " + parts[1]);
53		* System.out.println("Raw name: " + parts[2]);
54		*
55		* support.popContext();
56		* </pre>
57		*
58		* <p>Note that this class is optimized for the use case where most
59		* elements do not contain Namespace declarations: if the same
60		* prefix/URI mapping is repeated for each context (for example), this
61		* class will be somewhat less efficient.</p>
62		*
63		* <p>Although SAX drivers (parsers) may choose to use this class to
64		* implement namespace handling, they are not required to do so.
65		* Applications must track namespace information themselves if they
66		* want to use namespace information.
