Test cases for proposal: unrecognized attributes in the xml namespace should be ignored.

This closes ACTION 2002-01-18#2

The first test case covers the xml: namespace with examples of
xml:space and xml:foo generating no extra ntriples.

The second case uses an attribute that XML reserves - xmlnewthing and
shows it generates no extra ntriples.  Not sure if this one should be
there; let me know.
