UHD Blu-Ray: Allowed resolutions for HEVC, mandatory audio formats and HDR formats?

I am trying to find information on the above but haven't been successful so far. Most sources are either ambiguous or refer to the original Blu-Ray, so I thought it doesn't hurt to ask here:

- What are the allowed resolution-framerate combos allowed for HEVC? Is 1920x1080 at non-HFR framerates (23.976p, 24p, 25p, 30p) allowed to be in HEVC (or only H.264)?

- Is Dolby Digital Plus (aka E-AC3) with Atmos audio a mandatory format or does it have to be accompanied by a Dolby Digital (aka AC3) stream like on the original Blu-Ray?

- What HDR formats are mandatory, aka don't need an accompanying stream? By "HDR formats" I mean things like HLG, HDR10, HDR10+ etc

- Also, what do I need to write 100GB UHD Blu-Rays? I mean things like writers and blank discs. Can BDXL writers and blank discs be used to produce compatible 100GB UHD Blu-Rays with the right software?

A: Table 2-3: HEVC Main10, High Level 5.1 max.100Mbps 1920x1080, 3840x2160 @23.976p,24p,25p,50p,59.94p
MPEG-4 AVC High/Main Level 4.1/4.0 max. 40Mbps 1920x1080 @23.976p,24p

D: BD-R XL 100GB: Best resource seems makemkv forum. It looks as if only one Panny player (UB-900?) was able to play TL BD-R discs, the others seem to lock that out.

Wait, Dolby Vision is a mandatory HDR encoding? Because in Blu-ray you can put anything you want as optional (there is lots of space), it's the mandatory things I care about.

Nope... But as of Feb 2016 regular HDR10 is (for commercially released content)...

No, it is not mandatory.

It's HDR10 for commercially released 4K UHD discs. As previously mentioned!
