In general UPA violations are easily solved if you rewrite the ambiguous model in a non ambiguous way. In your case

<!ELEMENT item (risid,(waiting|passing|(waiting,passing)))>

can be written as

<!ELEMENT item (risid,((waiting, passing?)|passing))>

Yes, this is exactly what I need.
Thanks.

and the corresponding schema will be valid.

Hope that helps,
