Tag-insight question

[madde001]

Relax NG (as you know) allows elements and attributes from other namespaces to appear in a schema. When using this feature to incorporate other vocabulary into an RNG schema, is there any way to add that vocabulary to oXygen's RNG tag-insight list?

For example, let's say I was using xhtml vocab to embed documentation in an RNG schema. Is there any way I could reference the xhtml schema and have namespace-qualified xhtml elements appear alongside the native RNG elements in the tag-insight dropdown? Or in the case of embedded Schematron, could I reference the Schematron schema and have those elements added to the tag-insight list?
