Reading your doc i'm not really sure, is the actual implementation and
maintaining the format / importer is in your plans?

As for feedback, it's not really clear which exact aspects of current
format you consider most problematic and how you're proposing them to
solve. The only thing which is currently not met to your requirements is
compressed/binary mesh data, but it;s rather simple to integrate into XML.

I'm also not sure why human-readability should be a requirement. Not saying
we should not have human-readable format (in fact, we should have it and
default scene examples in repo should be rather in readable and easy to
tweak format), but i don't think it's something which should be used in
real production environment. Some binary format would solve lots of parsing
overhead and possible precision loss during parsing.

Imo, ideally it should also be some nice plug-in based system for parsing

Don't get it wrong, i'm really happy there's enthusiastic guy who's jumping
into this issue, just giving some preliminary feedback about areas of your
proposal which seems to be requiring more work.
