> Indeed. Are you proposing that Ulrich hold off on the current fix in favor of the new attribute scheme, or that he should fix this using the current mechanism for now (perhaps with a FIXME to upgrade to the new scheme once it is in place)? I would prefer for him to commit this now, and then upgrade later.

I don't have anything useful to say about Ulrich's fix since I didn't look at
it.  I just wanted to make sure that everyone knew where we are probably going:
in the direction laid out by Chris in those notes.

Ciao, Duncan.
