There is another reason for using simple content - you want an element to have both a value and element children. It's also not supported by DFDL 1.0 but it is something that is a candidate for the future, in order to handle a format that allows a complex element to have a nil value other than empty string. A schema definition error seems appropriate, as we don't want a behaviour change. I will add to agenda for next WG call.

Since attributes are not supported in DFDL, my vote is for schema definition error..

Should this return true (hey, a complex element can't have facets, so there are none to be violated), false (errors are false), or cause a processing error or schema definition error? Most conservative choice here is a schema definition error. -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com -- dfdl-wg mailing list dfdl-wg@ogf.org https://www.ogf.org/mailman/listinfo/dfdl-wg -- dfdl-wg mailing list dfdl-wg@ogf.org https://www.ogf.org/mailman/listinfo/dfdl-wg Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
