Lynx's DTD is built-in (and, conveniently, the people who did the building 
have moved on).  There's several places to change in the code for each 
element type, but it's reasonably systematic.  The only really (imho) ugly 
part is the large table in WWW/Library/Implementation/HTMLDTD.c after the 
comment "Extra element info" (it abuses enumerations to pack bits).

I've had in mind that if I ever have to do real changes there, I'll make a 
tool to dump the tables in that file into a readable schema, and generate 
the file from that.  So far, the only changes I recall are simple ones - 
adding entries to existing tables, and not trying to define new bits for 
that one.
