[Zope] XML Document: lower-case id-attribute exception

[Hans van Mourik]

When trying to add an XML Document instance
that has lower case id-attributes within tags
(eg. something like <para id="p001">)
Zope raises an exception (Error Value:
Invalid or duplicate property id). But when
the attribute is upper case, everything goes
allright (<para ID="p001">). This time the
XML-element instance has both a standard
Zope id-property and an ID-property.

Now maybe the XML parser that is used by Zope
could be altered somewhat so that it translates
to upper-case all occurences of an id-attribute.
