Re: Label and ID stuff

/ Innovimax SARL <innovimax@gmail.com> was heard to say:

Yes, I guess we could add a match pattern here.

You are required by the spec to fail.

In fact, I generate really ugly IDs of the form

  concat($prefix,'_',$hashcode,'_',$count,$suffix)

to attempt to avoid this problem. Hashcode is a unique identifier for
this particular label-elements component and count is just a counter
of the number if IDs I've inserted.

"Invalid" isn't our problem, IMHO.
