Hi Jan,

Thanks. It's still a "fist draft" ;-)

Well, I will check if that makes sense. I don't know if this will bring 
any noticeable benefit at the moment.

Right, I even did not think about this possibility. However in most 
cases there will be at least one package - that's why I put it like 
this. I changed it to allow 0 packages as well.

For WPKG it is perfectly acceptable to reference a single package 
multiple times - or even "included" through depending profiles. So no 
need to check that explicitly I think.

No. In fact it's referenced within the "profile" element. It allows to 
specify any number of variable elements.

Probably yes. As I said, it's my very first experience in XSD and it has 
been developed in quite a hurry during some night hours. So let me think 
about it and let's do one step after the other...
