Ok. I'll try to provide the 5.0 implementation status soon.
Attached is a first go for the 5.0 implementation status, just based on
Appendix B.
It cannot harm to proof read it – and extending it as follow up with
additional items and more details, implementation-specific behavior and
the like is useful and appreciated.
