Title: Who needs and uses XML Schema key/keyref?
We currently have a project using the CEN
13606-4-based healthcare messages where we are using DTDs and Schematron for
validation. When looking at porting to schema, the key/keyref structure
could be used for some of the directory look-ups but would not replace the
need for further validation against permitted ranges specified in the
message instance. A further significant area of validation that we are
having to do with Schematron (+XSLT extensions) is required date ordering
(service provided before message issue date)
the second pass is needed for the more flexible two tier xPath validation
that Schematron provide, there seems limited value in being able to move only
part of that into the schema.
is somewhere between speculation and use of the feature, but I trust close
enough to your primary interest
