IIUC, all of them. So...

...15. Rationale: existing capacity:* spaces are not usable unless you 
meet the criteria, but are (AFAIUI) included in capacity. The 
description in JOSM is explicitly "capacity (overall)". On the wiki, it 
is "the number of vehicles a facility holds". Both imply total capacity, 
including spots that aren't usable to many vehicles. It seems clear that 
the intent is that "general" capacity is the overall capacity less any 

It's possible that some software will need to adapt (though I question 
how critical it is to know capacity, since no software can know how many 
spaces are already occupied), but it's also possible such software is 
already not honoring other, existing capacity:* tags.

Hmm, "loading" would be good for curbside pick-up, though now we're into 
the discussion of whether a space for standing-only is actually a 
"parking" space :-). As for the main thrust of your question, see above.

Yeah, that might make sense. I'm not sure if it's better to go ahead and 
add that, or if we should treat each type as a separate proposal. (I'd 
almost be tempted to yank "compact" again and resubmit it as a follow-up.)
