W3C Schema Validation does not cater for xs:unique constraints about woodstox HOT 2 OPEN

Thank you for reporting this. I do not know for sure whether this is supportable: since actual validation logic is provided by MSV (multi-schema validator), that would give the ultimate truth. If MSV supports this, it should be supportable by Woodstox.

But I suspect the problem is that use of xpath expression for definition might require access to full tree model (dom), and if so, it would not be supportable with streaming(-only) parser.

For what it is worth, Woodstox is using the latest release of MSV, 2013.6.1:

http://mvnrepository.com/artifact/net.java.dev.msv/msv-core

otherwise only found this:

https://java.net/jira/browse/MSV-24

which could suggest that validation is not supported.
On the other hand, limitations spelled out in:

https://github.com/kohsuke/msv/blob/master/msv/doc/commandline.html

do not mention that this is missing, unless I misread it.

So... not sure whether msv provides for it. But even if it does, it is quite possible Woodstox is not feeding all information necessary if so.
