Great, I get to play translator again:
What the Soapy guys are trying to get across is that HTTP 1.1 doesn't provide
any specific guidelines or standards at the API level of a typical
application. SOAP does. One disconnect is that SOAP would typically use HTTP
1.1, which you are advocating, so it's unclear what you are trying to say in
that regard. Another disconnect is that HTTP 1.1 is a raw transport with
certain negotiation and commands but no standard determinant way to build
specific APIs. You do have both kinds of form submission standards (GET and
POST) but no complex data type encoding or organization of results.
On the other hand, SOAP doesn't seem to have a mechanism to reuse the MIME
negotiation machinery at the API and sub API level. That's the only point of
view where what you are saying makes sense to me.

Unless all you have a API's with a few simple text arguments that return
unformatted blobs of text/html, you need something more. You can return XML
or whatever and interpret it any way you want or return a SOAP style response
and have a standard way to find fields, data types, arrays, etc.
As I see it, SOAP is just the barest standardized usage of XML but that's good
enough to avoid a fair amount of wasted time reinventing that veneer each
