String with in-scope namespace binding information.

In a general case, text (PCDATA/attributes) that appear in XML schema cannot be correctly interpreted unless you also have in-scope namespace binding (a case in point is QName.) Therefore, it's convenient to handle the lexical representation and the in-scope namespace binding in a pair.

Resolves a namespace prefix to the corresponding namespace URI. This method is used for resolving prefixes in the value (such as when value represents a QName type.)

If the prefix is "" (empty string), the method returns the default namespace URI.

If the prefix is "xml", then the method returns "http://www.w3.org/XML/1998/namespace", as defined in the XML Namespaces Recommendation.

Returns: namespace URI of this prefix. If the specified prefix is not declared, the implementation returns null.
