Provides the evaluation context for fast execution and custom variables resolution.

Empty XPathNodeIterator, used to represent empty node sequence. Can be used to return empty nodeset out of an XSLT or XPath extension function. Implemented as a singleton.

IndexingXPathNavigator enables lazy or eager indexing of any XML store (XmlDocument, XPathDocument or any other IXPathNavigable XML store) thus providing an alternative way to select nodes directly from an index table instead of searhing the XML tree.

Implements a cache of XPath queries, for faster execution.
