Reproduced.
There's a path expression appearing in the definition of ComplexType Q{http://docs.oasis-open.org/wsn/t-1}TopicType, and Saxon is checking that the elements named in the path can legally appear in a valid document. In the case where the complex type contains a wildcard child element, all elements can legally appear, but this condition is being handled incorrectly.

- Category set to Schema conformance
- Assignee set to Michael Kay
- Applies to branch trunk added
- Fix Committed on Branch 9.9, trunk added
Fixed in 9.9 and trunk. Caller of complexType.gatherAllPermittedElements() should check that the returned set does not include "-1", indicating a wildcard in the type definition that prevents more detailed checking of path expressions.

Great, many thanks! When do you expect the fix to be generally available?

This one is sufficiently severe that it justifies a new maintenance release, so we're going to try and schedule that in over the next few days.
