#2003-06-25: nwalsh: Added translationloc, preverrataloc, rfc2119
#2003-05-28: nwalsh: Added errataloc, fixed IE bug. Added @num to prod.
Published V2.4
#2003-03-12: nwalsh: Added local.* PEs to a number of additional
places to make customization layers easier.
Published V2.3
#2002-09-04: nwalsh: Added 'phrase' to title, subtitle, version,
w3c-designation, w3c-doctype, day, month, year, name,
affiliation, email, language, role, lhs, rhs, com,
typename, date, loc, nt, sub, sup, term, termref,
titleref, xnt, xspecref, xtermref
This is *solely* to support automated diffing. Users
are explicitly forbidden from using this as an escape
hatch to get extra markup in these contexts.
#2001-10-08: nwalsh: Added local.arg.att and local.proto.att
#2002-08-14: nwalsh: Published V2.2
Added marked sections around element and attlist declarations and
