+Summary: DataSet.Clear should not enforce constraints
+
+Description of Problem:
+When you Clear() a DataSet containing parent - child relationships, Mono
+throws an InvalidConstraintException.  No actual data rows need to be in
+the dataset.
+
+This is different behavior from MS .NET Framework v1.1.  They apparantly
+suspend constraint checking while clearing the dataset.
+
+This incompatibility breaks my company's web application.  Bummer.
+
+Steps to reproduce the problem:
+1. Create a DataSet and define relationships between tables.
+2. call DataSet.Clear().  Note that you don't need to add any rows to the
+dataset at all!
+
+Actual Results:
+Throws InvalidConstraintException
+
+Expected Results:
+clear the dataset; do not throw any exception.
+
+How often does this happen? 
+Every time.
+
+Additional Information:
+Will attach test program.
