We didn't do it in previous releases (1.0 and 1.0.1) because it is a change rather than an addition. I believe we need a default policy of not changing attribute names without ensuring that all software implementers agree with it, since it will require software changes, XML schema changes and it will invalidate any existing DV_ENCAPSULATED data instances (but there may not be many or any yet). So we have to be careful with changes like this.
The mechanism we have for this is the implementers list. I have accordingly posted Rong's message there to create a thread allowing implementers to have their say. If there are no strong objections we can raise a CR. There may however be objections, and we may have to stick with the name as it is for this reason.... - thomas beale
