I was looking for a name, and I found weight as well as a good choice.
Mmmh... "impact" has the underlying meaning that it will have some negative effects on some existing applications, which is not the case for 99% of changes (we are careful about back compatibility).
I have check the weight definition, and I found "Gravity" as another choice.
Has something be define in Forrest's DTDs in this area?
It is not, but I guess, that if we find a good choice, I am happy to add it.
