I am copying the Maps for HTML community list to solicit opinions if any.

It will have some effects on software already out there that will need fixing (GeoServer, MapML Validator, web-map custom element), but I guess it's a work in progress.

I entered an issue for resolution here: https://github.com/Maps4HTML/MapML/issues/44 

Thanks,
