Re: <xsd:sequence>: whats the advantage?


xsd sequence
Also,
1.   the items in xsd:all must have maxOccurs=1 (minOccurs may be 0 or 
1), while the items in xsd:sequence may have other values of both min- 
and maxOccurs. 
2.  Similarly, the all group's min- and maxOccurs are restricted 
compared to those of the sequence group.
3.  The items of an all group may only be element declarations, while 
sequence items can include other groups such as choice, all, sequence 
and wildcard.

A sequence can express a much more complex and flexible content model.
