This question has been asked many times, and capabilities of this sort 
were seriously considered.  Experience with SGML, a precursor to XML that 
had more general "all" capability, showed that parsing of such structures 
can be much more complicated than the techniques used with the existing 
XML schema structures.  Indeed, early versions of XML schema drafts had no 
"all" capability at all.  The current limited support was added to provide 
a facility that would be useful in many common cases, but that would not 
be too hard to implement.

        Subject:        strict order in sequence

I would like to allow a client to provide me with full information, but 
in the strict order as <sequence> requires. May be it would make sence to 
add an attribute to sequence like 'strict' or 'order' with true/false 
value; or allow the use of <all> not only at the top level.

A Shunsky.
