A method and system for mapping a tag in a markup language (ML) document
to a class using namespaces is described. A parser in a computing system
analyzes the tag in the ML document. A definition file location attribute
related to the tag is referenced in the ML document. A definition file
associated with definition file location attribute is retrieved. A
namespace related to the tag is referenced within the definition file to
determine the class associated with the tag. The class is located in an
assembly such that the tag is mapped to the class.
