I think that ">>" should be used instead of ">" (as in the previous
representation), because of its greater visibility.

This may be heresy, but it would be all right with me if the pattern
version wasn't represented in the non-XML syntax: any file containing
just a pattern can be prefixed with "start =" with no effect on

I continue to think that a bare curly-braces-block should be mapped
to div.  Some work would be needed after a datatype name and after
include, which are (?) the only places that make a block optional.
