it seems to be a real bad idea to let people actually remove any type of IPR statement that might have been relied upon by a WG in any way and since its hard to figure out if thats the case, it seems like a real bad idea to let someone remove a IPR statement at all having a way for someone (properly verified) to mark the statement as no longer in effect (with a reason as to why) might be OK except that I find it hard to see why the IETF would want to make it easier for an IPR holder to mislead a WG on the IPR holder's intentions ('you can have it' 'oops, I did not mean that') there could be a real issue if someone who did not have the authority to do so committed a IPR holder to specific IPR terms (like free) but that seems to be a problem for the IPR holder to deal with internally since I'm far from sure what the legal precident is for that sort of thing Scott _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
