Thanks for the swift reply.

Now that I follow the reasoning, I'm suprised it worked in 0.5.5 too. I'll
rework the problem, perhaps using a modified file object to surround the
fragment with an arbitrary root tag, then extract the fragment from the
DOM. Not as tidy as I'd hoped, but I take heed from your warning that
doing it the other way would be abusing sgmlop. I'd hate for someone to go
and 'fix' it on me :)
