I don't quite understand how this list of questions arises as being the 
key questions, or maybe just I don't know which user segments we are 
addressing.

If it's 3/4/5+C, that segment assumes a library, and we have two forms 
of that: a one step specific-parser to produce a JS structure that the 
app can use, or a full-blown library where access is always via a 
library call. Either way the format on-the-wire isn't directly visible 
to the application.

Which is this addressing?  On-the-wire or JS structure?  I'd answer the 
questions differently for these 2 cases.
