This module defines an internal (generic) representation for XML documents including their DTDs.
History: The original module was derived by hand from the XML specification, following the grammar precisely. Then we simplified the types, removing layers of indirection and redundancy, and generally making things easier to work with. Then we allowed PEReferences to be ubiquitous, by removing them from the types and resolving all PE references at parse-time. Finally, we added a per-document symbol table for GEReferences, and a whitespace-significance flag for plaintext.

Namespaces
A QName is a (possibly) qualified name, in the sense of XML namespaces.
Namespaces are not defined in the XML spec itself, but at http://www.w3.org/TR/xml-names
