Just to add a bit more detail, the main limitation of xs:all is that 
minOccurs and maxOccurs are restricted to be either 0 or 1.  Also, xs:any 
style wildcards are not allowed, nor can xs:all be or have anonymous 
compositors.  And it can't be used in extension scenarios.  Hence it might 
be a bit limiting for your needs.  (BTW - some of these limitations maybe 
relaxed in XSD 1.1, but I wouldn't wait for that to come along!)

I'd also recommend the book Andreas mentioned:
http://www.amazon.com/XML-Schema-Eric-Van-Vlist/dp/0596002521/

Although, some reviewers seem to think it's not the best text to start with.

HTH,

Pete.
