Subject: [PATCH] Fixes #44: Two prefixes resolving to the same namespace
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The new TreeBuilder addition seems to have fixed this bug. I added the
test that was provided in !108 by Oliver Inemar but not the rest of the
code.
