This is actually not how default namespaces work.  The default
namespace does not apply to XML attributes.

Some NETCONF servers are lax and will accept an unqualified
"operation" attribute.

This is the only example so far that is correct.  It is important that
the "ElementA" has a namespace declaration; otherwise it refers to
"ElementA" in the namespace "urn:ietf:params:xml:ns:netconf:base:1.0",
which clearly is wrong.
