Yes, html--syntax-propertize-submode would search for the end of the
sub-region (only up to `end`, of course), mark the found area with
a text-property, and then call the sub-mode's syntax-propertize-function
on that area.

Yes, you need to filter out the elements you don't want, or pick the few
elements you do want.  But I think you're better off manually
maintaining a list of relevant variables, than manually maintaining not
only which variables are relevant but also the values used by each of the
sub-modes (which in turns causes circular dependencies between the
packages).
