This patch addresses bugs 1013525
("xml.dom documentation omits createDocument,
...DocumentType")
and 1010196
("xml.dom documentation omits hasAttribute,
hasAttributeNS")

In the documentation for createDocument(), it is now stated
that the Python DOM API allows implementations to forego
creation of the document element child node, if no
namespace
and local name arguments are given. (This possibility
is left
open and unaddressed in the W3C spec).

The patch also fixes a broken reference to an external
document,
and adds a mention that the Python DOM API does not require
enforcement of W3C DOM requirements that are not accounted
for in the IDL definitions upon which the Python mapping is
based.

The patch was developed against Python 2.4b1's
/python/dist/src/Doc/lib/xmldom.tex and is untested.
