+Summary: DataSet.WriteXml doesn't allow for special characters in column names
+
+Description of Problem:
+Special characters in column/table names are rendered incorrectly for a
+DataSet schema using WriteXml, causing an exception when trying to read it
+back.  The data looks like it translates the names correctly, however.  The
+special characters that I found cause a problem are '#', '<' and '>'. 
+There may be others.
+
+Steps to reproduce the problem:
+1. Compile the attached file (.cs)
+2. Run the resulting executable in mono
+
+Actual Results:
+The schema that is written does not translate the 'special' characters the
+same way it is done when writing the data.  The program throws an exception
+when trying to read the schema. 
+
+Expected Results:
+The schema xml should have the same translation done on the column names as
+is used when writing the data, so that there are no errors reading back the
+dataset.
+
+How often does this happen? 
+Every time
+
+Additional Information:
+Here is the exception that is thrown:
+
+Unhandled Exception: System.Xml.Schema.XmlSchemaException: XmlSchema error:
+attribute name must be NCName Related schema item SourceUri: , Line 10,
+Position 18.
