XML Schema (XSD) and ADO.net DataSet - limitations mapping between them

TheMSsForum.com: The Microsoft Software Forum

The following valid XSD schema can NOT be successfully read by the
ReadXMLSchema method of the DataSet object - it errors out with a
"NonEmptyString not defined" error. This schema is more complex than a
plain vanilla schema, but doesn't strike me as obscenely complex.

Are there general rules for what can an can not be mapped between any XSD
schema & a .net DataSet?

Thanks

in 1.0 and 1.1, DataSet does not support named simple types.
DataSet 2.0 Beta 1, processes below provided schema.
