Maybe, but the fact that the ItemIdData struct consists of bit fields
that are all named "lp_*" offers a hint. Plus you have the LP_*
constants that get stored in ItemIdData.lp_flags.

I wouldn't call the struct ItemIdData if I was in a green field
situation, but it doesn't seem too bad under the present
circumstances. I'd rather not change the struct's name, because that
would probably cause problems without any real benefit. OTOH, calling
two closely related but distinct things by the same name is atrocious.
