I became aware of this when I was trying to port the maintenance branch
layout into the trunk. It is, in fact, the issue that stopped my progress
when I was last able to work on that project about 8 weeks ago. I hope to
get back to it again sometime in the next week or two. It appears that IDs
were implemented in maintenance branch code, but never in the trunk. I was
just starting into figuring out what the new design is, when I got
sidetracked. I suppose that the correct approach in the new design is to use
the TRAIT constructs that you have noted, but I am not sure. If anybody
knows how this is *supposed* to work in the new design, please let me know.

The short answer is that I think this problem will eventually be fixed, but
I am not sure when.
