Hi,
Hopefully this diagram will make explicit some of the CRS considerations that MapML is trying to address:

Sorry its not a responsive image!
There are other changes to the spec, certainly not all of which are implemented yet, but you should have a look and please let me know if you see errors or have comments.
https://maps4html.github.io/MapML/spec/#sotd
Of particular note is that I think the input@type=xmin,ymin,xmax,ymax and projection are no longer needed, so I've marked them as deprecated. The bounds related inputs can be
accomplished with input@type=location + related attribute values and input@type=projection can be accomplished with input@type=hidden.
Anyway there's lots worth discussion there. Open an issue or discuss here.
Cheers, and thanks,
Peter
