Item10287: Meta should only store registered element names without a leading underscore (_).

I'm actually thinking to only serialise those things that are registered....

otherwise life gets much harder for non-stuffitintotext backends

Agreed - I think, on the assumption nothing breaks. The leading _ was my pathetic attempt at defending internal fields from the mess that was the Meta module, and predates VALIDATE by several years. I would certainly not be sad to see it go (or at least be de-emphasised).

I've commited the change (only to ignore anything starting with _ ) - I'll contemplate more later.

Nothing else is going to happen on this for now, so closing.
