>Adding minOccurs="0" still didn't do the job. But thank you for the suggestion.

Dmitry, the only point I was making about using minOccurs="0" was that it would allow the XML to Validate if it was missing the req_entry tag, which is what Viv was complaining about.

However, using minOccurs="0" won't work for you because then it definitely doesn't use the default if you omit the req_entry tag (your current schema doesn't specify a minOccurs, and I believe that defaults to "1").

If default is specified, and if the element being validated is empty, then the canonical form of the supplied constraint value becomes the schema normalized value of the validated element in the ·post-schema-validation infoset (my italics)

>>>Looks to me as if .Net has decided to define its own behaviour as far as the DataSet goes - and I guess I can see the reasoning - being able to omit elements could drastically reduce the XML size. But that still means that, even though the XML might create a valid DataSet if you attempt to pre-validate it against the defined schema it will fail :-{
