Agreed. As such, the language I've written below doesn't present Interfaces as having Bindings (and therefore Transfer Codings). Rather, it presents the binding rules (including matching the interface name associated with the Binding) where the Transfer Coding property values/defaults are applied. It is possible that the way it is written is confusing, so I have modified the language below as a clarification.

Agreed. The language below (as clarified, please review :-)) implicitly states this point. My understanding is that the point is made as is (pursuant of language which explicity states the meaning of a Binding specifying an Interafce). 

However, if this is not clear enough as is, we may need to better elaborate this in these paragraphs. Please let me know what you think. 

Best,
