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. len From: Mike Fitzgerald [mailto:mike@w...] 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?
