Hi Mirja,

Thanks for your comments.  Please see inline.

It could be a subsection, but I think it fits well as flow within the section.

It was originally there, but was moved here 
because that draft is more focused on eCall, 
while this draft is the more general extension, 
so it seems to fit well here.

I rewrote several sections of both drafts to 
remove unnecessary redundancy to dress Alissa's 
review comments prior to IESG submission.  If 
there are additional edits you feel would enhance 
the readability, please let me know the specifics.

Thanks for catching this, I appreciate it.  This 
was an error that was introduced when the 
specific actions not needed for eCall were moved 
into this draft and made more general.  I've 
fixed it by readding the "door-lock" action and 
the text explaining that the "requested-state" 
attribute is set to "locked" or "unlocked".

Well, it's already been suggested that changing 
color might be added, but I agree that we 
probably don't need the registry.  I'll specify 
the three values now.
