But to stress...the ideas I am playing with concern re-using the CSS
*processing model*. Say we factored out the processing model from CSS
and called it 'dynamic infoset', or some such. We would then have a
mechanism that allows us to create rules that say 'select these
elements and add this property to them and set it to this value'. That
would be incredibly useful in many contexts.

But then also, a new version of CSS itself would be written, that
says, 'this spec uses the concept of a dynamic infoset' and would
refer to this other spec. And whilst the dynamic infoset is about a
generic solution, CSS is about specific properties with specific
meanings, like 'color: blue;'.

(And to also stress, I wasn't imagining that this issue would be
resolved here. I only raised it because I felt that Dmitri's idea was
being dismissed for the wrong reasons.)
