XML Namespaces
--------------
This module has support for XML namespaces as defined in the XML
Namespaces proposed recommendation.
Tag and attribute names that are defined in an XML namespace are
handled as if the name of the tag or element consisted of the namespace
(i.e. the URL that defines the namespace) followed by a space and the
name of the tag or attribute. For instance, the tag `<html
xmlns='http://www.w3.org/TR/REC-html40'>' is treated as if the tag name
was `'http://www.w3.org/TR/REC-html40 html'', and the tag `<html:a
href='http://frob.com'>' inside the above mentioned element is treated
as if the tag name were `'http://www.w3.org/TR/REC-html40 a'' and the
attribute name as if it were `'http://www.w3.org/TR/REC-html40 href''.
An older draft of the XML Namespaces proposal is also recognized, but
triggers a warning.
