Interesting.
I have always (without asking) considered the word choice of "processor" to be intentionally chosen to NOT imply "parser".


That is, it *processes* XML ... which may or may not be "parsing"
Or else "they" would have used "parser"
Isnt "XSLT" considered a "processor" even though it is not a "parser" ?

Maybe that is why there is no requirement for "processors" to do things like report elements.

Maybe it would be good to break from tradition and make the words explicitly different so nincompoops like myself can tell them apart.

"parser" - A program which exposes the MicroXML document as an API corresponding to the Abstract Data Model
"processor" - A program which processes data in a MicroXML document for some result (not enumerated by the spec), 
  but implies the result is created according to (conformance with) the MicroXML  Data Model.

As for Fortran Vs C ... you totally lost me but thats fine.

Historically these terms have always meant the same thing in the SGML/XML
world.  But if you want to distinguish them, fine; the abstract data
model and MicroXML conformance pertain only to parsers.

The GNU, BSD, and Solaris versions definitely are, provided you set the
locale correctly.

It's absurd to suppose that a Fortran compiler conforms to C.  The fact
that you want to compile Fortran has nothing to do with that judgement.
Similarly, programs can process MicroXML without needing to be conformant
parsers.
