This is a limitation of the System.Data.DataSet class when it tries to infer relational structure from a W3C XML Schema document. The article at http://www.fawcette.com/xmlmag/2002_07/online/webservices_rjennings_07_29_02/default_pf.asp describes a number of workarounds to problems in the schema inference process.

Subject: error creating a dataset from schema

Hello all,
I'm new to the list and this question is specific for .NET. I'm trying to create a
dataset from my xsd file, but I get the following error:
The same table (identityInfo) cannot be the child table in two nested relations.
I validated the xsd file with XMLSPY and it is okay, also I find no way of representing
that relationship. I have three tables on my database (ThesisAuthors, ThesisSponsors and
ThesisTutors) and all of them have the identityInfo table as a child.
Any ideas of why I'm getting this error?
thanks in advance,
