I absolutely think that requiring CSS is too much. I was thinking
of somebody implementing ITS as a Firefox extension, for example.
That kind of implementation would have access to CSS properties.
I viewed it as sort of like getting a fixed value from a DTD or
an XML Schema. You don't have to implement those, but if you do,
you can use the data they provide.

Thinking about it more, though, if we allowed optionally setting
ITS Preserve Space from CSS white-space, then we should allow
setting ITS Directionality from CSS direction.
