[Bug 4487] [XDM] Missing constraint for attribute names

I don't understand why this situation is any different to having an attribute
with a namespace prefix that cannot be used since the prefix is already bound
on the same element to a different namespace URI. In both cases the XDM
shouldn't care, because the prefix is irrelevant to the actual name of the
attribute (the namespace URI/local name pair).

In my opinion this situation is a serialisation issue, and should be dealt with
during serialisation. I think the obvious solution is to make up a namespace
prefix for the attribute in both cases - but an alternative solution is to
raise an error.
