The XPath engine has full XPath context support and uses the .NET Framework's XsltContext class in the same way that XPathNavigator does to implement this support. XsltContext is an abstract class that allows developers to implement custom XPath function libraries and declare XPath variables. XsltContext is an XmlNamespaceManager and thus also contains the namespace prefix mappings.

The filter engine implements an XsltContext named XPathMessageContext. XPathMessageContext defines custom functions that can be used in XPath expressions and it declares several common namespace prefix mappings.
