This point looks correct to me at an abstract level (i.e conceptually). I
like the term 'some value-add', and I do agree to this terminology. But,
isn't imposing only one order on XML elements to be validated with
<sequence>, hasn't got a semantic meaning? I think it does.

This is true. I think, as the number of XML elements (which are sibling to
each order) grow more, this point is even truer I think. But it would also
depend on the implementation strategies used by the XML Schema processor.
