Based on a quick scan of the XMLSec WG's mail archive [2], it appears 
that WG has known about potential IP issues related to Certicom/RIM and 
ECC for almost 3 years. As such, surely the WG has already discussed 
refactoring the XMLSig spec in a way like Marcos and I proposed.

Would you please explain why the WG objects to such refactoring (or 
provide a link(s) to the related discussion)?

As an FYI for the XMLSec WG members, note that another widget spec was 
blocked for two years because of a PAG [1] so it's quite understandable 
that having widgets-digsig blocked by YA PAG creates concerns for some 
WG members, especially given the ECC PAG Chair's "pessimistic" view [3] 
of a "quick" PAG resolution.

-Thanks, AB
