LEXX is essentially designed for Dictionary (English Dictionary - I
think the Oxford ED) writing originally.

It is not a power editor and is quite slow (at least the implementation
I have seen a couple of years back at IBM). It is also an IBM IUO (i.e.
Internal Use Only) and hence is not available for general public even
if one is ready to pay $s.

It is completely tailorable but is most powerful in displaying the
SCRIPT/VS documents. One possibility that you haven't seen it working
for PL/I may be because it has complete support for SCRIPT and nobody
has time to do it for other languages. But given REXX and LEXX one
should be able to write the macros for any language.
