So it's just HTML? Is there a reason (legal or otherwise) that they can't just use HTML?

It's not like HTML except for being XML which looks a lot like SGML.

It's significantly more limited and more specific to the task than HTML. HTML comes with a lot of baggage that makes it unsuitable for a really specific use case.

I think it's interesting that Apple is promoting making apps that are web based that you wouldn't have to get approval for to make updates. Maybe because it's limited on you can do with TVML but I think it's interesting.

Supporting full HTML would much be more processor- and memory-intensive. It also gives developers more freedom, which can negatively impact the user experience.

I don't know if I agree with the tradeoffs they've made here, but those are at least two reasons to create their own custom schema here.

I'm a little surprised they're jumping into the literal "TV" namespace so wholeheartedly.

Is the future of this ecosystem really exclusively limited to the Television?

Gaming is already an explicit part of this, which undoubtedly will include VR, which is theoretically suited to Television-like content.

If they do this right, the source code running on your VR gogs will mention "TV" everywhere, much like the the current OS running their desktops and mobile devices references a defunct company.

XML does not only look a lot like SGML, it is a proper subset of SGML:

XML is an application profile or restricted form of SGML, the Standard Generalized Markup Language [ISO 8879]. By construction, XML documents are conforming SGML documents.
