I think that using<br>

only negated slot names make sense in combination with '*'. This,<br>

That is true, the * could be considered explicit if you have one ore
more negated slots.<br>

Therefore, only a list of all positive <i>or </i>all negated
slot names makes<br>
sense. Thus, all possible sets can be defined by permitting
nothing<br>
but one of these forms:<br>
onChange == [<name>,...]<br>
onChange == [*]<br>
onChange != [<name>,...] // subtract all enumerated
from full set<br>

One can also permit these two identical forms:<br>
onChange == []<br>
onChange != [*]<br>
and<br>
onChange != []<br>
which is the same as<br>
onChange == [*]<br>

yup, I like those ideas too. I'll get the wiki updated with them.<br>
