Yeah the comment looks wrong to me.  It probably relates back to Elliote's
implementation where a namespace may not return the prefix you think you
added because a previous prefix was added with the same namespace.  In that
case, it's anybodies guess which one you would get back. Perhaps this
behaviour has changed.  I'll run my tests to see soon.  It seems that the
was the code is written is what a user would actually expect.
