XSD - maxOccur greater than one, but order not important
I'm looking for a way to define an XSD schema for an element where it can contain a number of different elements, where one element can appear multiple times, but the order does not appear.
Or, to put it more simply, I'm looking for something like xs:sequence were the order does not matter, or xs:all where an element can appear more than once.
It seems like the type of question that must have been asked a million times, but I can't find an answer.
Ooh, they have the Internet on computers now!
