... because I wanted to check first if it's a known bug, and if it isn't, submit a bug report in the bugzilla.

I can understand that you don't want people to email libxml related stuff to you directly, but I don't think it's *ever* appropriate to post contents of private emails to public lists.

It may be well-formed, but I don't think zero-length prefixes are legal.
  [2] PrefixedAttName  ::= 'xmlns:' NCName
  [4] NCName  ::= (Letter | '_') (NCNameChar)*

For sure.

Exactly. In addition to probably violating the namespaces spec, the document is invalid in respect to the referenced DTD.
