Host Meta and XRD, POWDER (ISSUE-36 ,siteData-36)

"3. The host-meta Document Format


   The host-meta document uses the XRD 1.0 document format as defined by
   [OASIS.XRD-1.0], which provides a simple and extensible XML-based
   schema for describing resources."

This pretty clearly overlaps with POWDER. I wonder why it wasn't caught at
CR or even much earlier.

Did the W3C POWDER WG neglect to engage a relevant part of the community?

Is a significant community producing things like site copyright policies 
with POWDER?
If so, and Host-Meta with XRD gets deployed, then consumers will have to 
support both formats.
That seems like a pretty clear standardization failure.

Copyright in particular isn't shown in the primer, but lots of other 
nearby stuff is:
