entity invalidation

Dear all,

Following last week's teleconference, Paul, Paolo, Tim and I have 
revisited the proposal on
invalidation.

Your feedback would be useful. Can you express in the usual way if you 
support it? and if not, what
issue you have this proposal.

If there is support, we would like to consider this section as part of 
the prov-dm release, provided
that we can also adjust prov-o and prov-n.

Regards,
Luc
