Thanks for clarifying.

Since a SHOULD requirement is optional, I don't think it necessarily  
raises critical patent concerns. For example, Apple's experimental  
implementation of <video> does not support Ogg Theora.

That being said, I think it is important for the W3C to explore this  
issue. And Apple would be in favor of removing the SHOULD as well (we  
think it is unhelpful to say implementations "SHOULD" do something  
that some of us "CAN'T"), but we do not consider it a showstopper  
requirement.

Regards,
Maciej
