Overview
The XmlParserContext class allows you to specify context details for the creation of XmlTextReader and XmlValidatingReader objects. Depending on which of the overloaded versions of this class you use, you can assign a number of different context values, including an NameTable, an XmlNamespaceManager, a base URI, xml:lang, xml:space, and an encoding type.
