Bug ID: 39004
           Summary: ISAXAttributes.getQName should return an empty string
                    for xmlns attributes
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: msxml3
          Assignee: [e-mail]

According to the specification ISAXAttribute.getQName should return an empty
string if "http://xml.org/sax/features/namespace-prefixes" is enabled and an
attribute is an xmlns attribute:

"For the "xmlns" namespace, the qname value is empty."
(https://msdn.microsoft.com/en-us/library/ms760423%28v=vs.85%29.aspx)

(If "http://xml.org/sax/features/namespace-prefixes" is disabled such
attributes are correctly ignored.)
