In Notes and Domino 11, HCL switched from using IBM's J9 Java distribution to using the OpenJ9 variant of AdoptOpenJDK. This is a lateral move technically - it's still Java 8 - and it's one presumably made in the short term to avoid licensing costs from IBM and in the long term to align better with AdoptOpenJDK.

After I did my initial port of my XSP completion assistant to LSP4XML, I got to thinking about improvements I could make to it. One of these was the notion of creating XML Schemas for a project's XPages, similar to how the DXL contributor just passes along the schema files that ship with Notes and Domino.
