You're claiming here that there is a requirement here to use TeX macros, namely use with pdfTeX etc.  But what you say does not impose such a requirement.

Don Knuth's WEB system uses a custom program WEAVE to create a TeX input file from a .web file.

It's perfectly possible to use a similar front end for processing documents written in the LaTeX syntax.

You snipped:

Surely to do this you will need a LaTeX->XML translator written in /some other language/.  And once you have that, why do you need an implementation written in TeX macros?

And come to that, the translator will surely want access to

Any comments here?
