In the case of our WICD profiles: mobile and full, full is a super-set
of mobile.  If full content were provided to a mobile profile only
capable device, then the mobile device would rely on user agent
conformance for handling unknown content.  Given that this fallback
behaviour would be XHTML fallback behaviour - "If a user agent
encounters an element it does not recognize, it must process the
element's content"[1] - we expect that much (though admitedly, not
all) full XHTML 1.0 content will be usable (though not perfectly
rendered, of course) by a typical end user.

We do not plan on making any updates to this section but plan on 
clarifying UA conformance criteria regarding profiled DOM specs.

We have coordinated with the WebAPIs WG to reference their forthcoming 
"Window Object" specification for parent-to-child and child-to-parent 
cross-document access.  We are still working on resolving the 
SecurityException, as the WebAPI WG hasn't closed on that.

We have decided to drop the specification of cross-document event 
propagation, instead we'll provide a description of how existing 
techniques can be used (dynamically adding listeners/handlers to 
propagate, etc.).

We'll change to more appropriate wording, such as "whether it bubbles"

Please let us know within two weeks if this reply doesn't satisfy your 
comments.
