... 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. But in this case it doesn't matter much.

Anyways: Please accept my apologies for bothering you directly. I'll exclusively use the list or/and bugzilla in the future.

  Your document is a correct XML-1.0 document.

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

The parser will not raise a well formed error.

If xmllint is namespace-aware, it might make sense to raise an error for zero-length prefixes.

It probably should raise a validity error

For sure.

and that may be a bug but it depends on the DOCTYPE since it's unlikely
taht an "xmlns:" attribute was defined in the SVG DTD.

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

Please check this first and log the bug in bugzilla
