I use them but given the actual fairly low application
of the XML Schemas beyond documentation, it is difficult
to determine if one could live without them. If
I can tighten it down and for example, the specification
for the data denotes occurrences, I carry them into
the schema for the sake of precision of mapping from the
natural language spec into the XML Schema-as-spec.
I don't know what the cases are elsewhere, but it seems locally
that most programmers prefer to avoid schema-based validation
and use their own code for that. I don't know if that is
"have a rock, all else are targets" or "YAGNI". It would
be interesting to see comparisons of different programming
cultures as to adoption of features of XML processing
compared to their learning curve and their actual needs.
I suspect that a signficant percentage still treat XML
as verbose comma-delimited ASCII.

Don't know, but I'd be interested to know. Who out there is using
minOccurs/maxOccurs in XML Schema beyond zero-one-many? Can you live without
minOccurs/maxOccurs or do you gotta have it?
