[oXygen-user] <import/> and validation

Thanks for your message.
Sure the <import/> should be validated, the XML Schema specification
specifically allows it:
NOTE: Since both the namespace and schemaLocation [attribute] are optional,
a bare <import/> information item is allowed. This simply allows unqualified
reference to foreign components with no target namespace without giving any
hints as to where to find them.
We already found the problem in oXygen and fix it. It was a bug in the
catalog resolver that rised an exception when the resource to be resolved
had all the fields set to null.
