Hi All,
In the sample schema & document below, I'd like the attribute "name" to
be unique for all function elements under function_list. The tools I'm
using (XML Spy and xmllint) all validate the sample document and do not
pick up that the name is not unique.
Any clues as to what could be going wrong?
Thanks.
