+/**
+ * <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><element xmlns:prefix="http://Namespace-name-URI"></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>
+ * <element xmlns:prefix1="http://Namespace-name-URI"
+ * xmlns:prefix2="http://Namespace-name-URI">
+ * </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>
+ * <parent xmlns:prefix1="http://Namespace-name-URI">
+ * <child xmlns:prefix2="http://Namespace-name-URI">
+ * ...
+ * </child>
+ * </parent>
+ * </pre></p>
+ *
+ * <p>A prefix can only be bound to a <strong>single</strong>
+ * Namespace URI in the current scope.</p>
