[Mondrian] Mondrian 4 XSD

[Diethard Steiner]

My best greetings to all of you!
If I remember Julian's words correctly from the Pentaho User Meeting in Amsterdam (and if nothing has changed since then), Schema Workbench will not be used any more for creating Mondrian 4 XML files. So, that's no problem for me as long as I can get hold of an XSD file to validate the XML. I could find a very old DTD and then also an XSD for Mondrian 3.x but no sight yet of anything related to Mondrian 4. Can someone please point me to the right direction?
Thanks,
Diddy
