If you look at section 3.7.2 of the structure spec [1], you'll find the
following (right before 3.7.3)
"Also note that in the first (named) case above no reference is made to
minOccurs or maxOccurs: this is because the schema for schemas does not
allow them on the child of <group> when it is named. This in turn is
because the {min occurs} and {max occurs} of the particles which refer to
the definition are what count."
This is clear that min/maxOccurs attributes are not allowed on
<all/sequence/choice> that's a direct child of a named group.

Maybe you should complain about XMLSpy. :-)

Could you be more specific? If there are such examples, the spec is in
error.
