Egad!  I didn't say that exchanged information doesn't deserve an API.
I'm saying a very, very different thing.

I'm saying that, for many kinds of information, attempting to derive
the API from the syntactic structure, or attempting to define the
syntax in terms of the desired API, are bad ideas.  The robustness of
the syntax will suffer, or the usefulness of the API will suffer, or
both, or you will throw up your hands and get disgusted with this
whole XML shtick, because XML is clearly not strong enough to deal
with your problem in a reasonable way.  Bad outcomes, all, and all
completely unnecessary.

In the general case, for any given kind of information to be
interchanged, we need:

* a model for the syntax of the information, *and*

* a model for the properties of the information, once it has been
  understood.
