According to (my interpretation of) section "3.8.2 XML Representation of
Model Group Schema Components" of [1], that is not the case. This
section states the following for the XML representation Model Group
Schema Components (all/choice/sequence):

- all: maxOccurs must be 1; minOccurs can be 0 or 1.
- choice/sequence: maxOccurs must be nonNegativeInteger or unbouned;
minOccurs must be nonNegativeInteger.
