Ok, based on the input given for PaceMediaEntries2, here is PaceMediaEntries3. I think we're definitely getting very close.
http://www.intertwingly.net/wiki/pie/PaceMediaEntries3 A number of incremental improvements. 1. Only specifies content/@src for the public reference URI. Still uses link/@rel=edit-resource to specify the edit URI. 2. Added "entry" value for app:accept, missing app:accept is equivalent to <app:accept>entry</app:accept>. <app:accept>image/*</app:accept> means ONLY image files can be posted. <app:accept>entry,image/*</app:accept> means that both entry documents and image files can be posted. 3. If provided, app:accept cannot be empty and must not contain leading or trailing whitespace. 4. Content-Location has been added to the examples to properly reflect the SHOULD requirement. 5. Cleaned out some of the old, no-longer relevant rationale from PaceMediaEntries. - James
