What can be done is to let the TeX syntax include "$base" for the  
command argument, that will include the base syntax file, so that'd  
be LaTeX when the document is marked up as LaTeX, and TeX when the  
document is TeX.

We use this e.g. in the C grammar, which has a few recursive rules,  
and is (sometimes) included by the C++ or Objective-C grammar.

Though not sure if there are other problems using the LaTeX grammar  
recursively (as I got the impression of, from Brads comment).
