This definition is missing, and we are going to need it to sanitise
TCR2_ELx.

This is correct in so far as it goes, but we are also mising HDBSS
according to the 2024-09 XML, plus a couple of new revisions of ETS.
I'll send a patch doing the full update, it should just be a trivial
add/add conflict.

It tends to make life a bit easier to note which version of the spec is
being referenced with these updates.
