RE: [Fwd: Question about complexType with unordered child elementswith at least one child element]

My guess below. Jing does not complain. But it also doesn't complain about
multiple instances of optional children or zero children of <whatever>,
perhaps only because Jing is not reporting an error on non-matches? I
believe the syntax 'says' what you want it to say, nonetheless. -Mike

I don't thing it's possible to capture this with RELAX NG either and I
was wondering if it's something that might be useful.

The condition to capture is "in the following sequence (or interleave)
of optional items, I want to be sure that there is at least one of these
items".

Or maybe I have missed something and it's already possible with RELAX
NG?
