Subject: Re: 7.1 and 7.3 are as bad as XML Schema
I agree that there is scope for improvement in 7.1, but I don't agree with you about 7.3. I think the informal concept is very straightforward, and I don't think the formalization is any harder than section 6. I also think the restriction is a very natural one. What we need from a restriction is the ability to uniquely assign key-types to attributes and elements. Our restriction uses the same basic idea as XML Schema's unique attribution constraint: the assignment must be uniquely determined by the ancestry of the element or attribute. It differs only in what is being assigned. This constraint may well be lacking from a theoretical perspective, but I think it will make very good sense to XML practioner ----- Original Message ----- From: "Murata Makoto" <mura034@attglobal.net> To: <relax-ng@lists.oasis-open.org> Sent: Thursday, July 26, 2001 9:00 PM Subject: 7.1 and 7.3 are as bad as XML Schema > I would like to know who in the TC understands 7.1 and 7.3.
