Hello, could you please clarify the semantics of the &-Operator for me: I understand, that: - XML Schema ALL-Groups are represented by the &-notation in XQuery - ALL-Groups in XML Schema may only contain Element-Nodes with MaxOccurs=1 as content - The & notation can be expanded to the interleaved product of its content items. However, the XQuery semantics document contains judgements like the following: - ElementContent & text* (Sec. 7.1.6) - Type3 & processing-instruction* & comment* (Sec. 7.1.8). How can the all-notation in these examples be expanded to an interleaved product? In particular, I do not understand how to handle the occurence indicators. Can type expressions be broken up? For example is the following expansion valid? (A,B) & C* == (C*,A,C*,B,C*) Thanks in advance, Robin Aly -- Robin Aly (robin@pi3.informatik.uni-mannheim.de)Received on Monday, 15 November 2004 16:09:14 GMT
