/**
* <p>Interface for read only XML Namespace context processing.</p>
*
* <p>An XML Namespace has the properties:</p>
* <ul>
* <li>Namespace URI:
* Namespace name expressed as a URI to which the prefix is bound</li>
* <li>prefix: syntactically, this is the part of the attribute name
* following the <code>XMLConstants.XMLNS_ATTRIBUTE</code>
* ("xmlns") in the Namespace declaration</li>
* </ul>
* <p>example:
* <code>&lt;element xmlns:prefix="http://Namespace-name-URI"&gt;</code></p>
*
* <p>All <code>get*(*)</code> methods operate in the current scope
* for Namespace URI and prefix resolution.</p>
*
* <p>Note that a Namespace URI can be bound to
* <strong>multiple</strong> prefixes in the current scope. This can
* occur when multiple <code>XMLConstants.XMLNS_ATTRIBUTE</code>
* ("xmlns") Namespace declarations occur in the same Start-Tag and
* refer to the same Namespace URI. e.g.<br />
* <pre>
* &lt;element xmlns:prefix1="http://Namespace-name-URI"
* xmlns:prefix2="http://Namespace-name-URI"&gt;
* </pre>
* This can also occur when the same Namespace URI is used in multiple
* <code>XMLConstants.XMLNS_ATTRIBUTE</code> ("xmlns") Namespace
* declarations in the logical parent element hierarchy. e.g.<br />
* <pre>
* &lt;parent xmlns:prefix1="http://Namespace-name-URI">
* &lt;child xmlns:prefix2="http://Namespace-name-URI"&gt;
* ...
* &lt;/child&gt;
* &lt;/parent&gt;
* </pre></p>
*
* <p>A prefix can only be bound to a <strong>single</strong>
* Namespace URI in the current scope.</p>
