No, but you can pass anything you want to the parser implementation's
constructors.

You could pass/store a reference to this data structure in the parser
implementation that handles the "name" attribute. This way you can change
the list of names between the parse sessions if you would like to reuse
the same set of parsers to parse multiple documents.
