Resolves namespace prefixes to namespace URIs.
The prefixes used within an XPath expression are independant of those used within any target document. When evaluating an XPath against a document, only the resolved namespace URIs are compared, not their prefixes.
A NamespaceContext
is responsible for
translating prefixes as they appear in XPath expressions
into URIs for comparison. A document's prefixes are
resolved internal to the document based upon its own
namespace nodes.
