You are right that it is an SGML DTD, not an XML DTD.  At this stage
(given that we don't yet have XML schemas and SGML DTD's are more
powerful that XML DTDs), this seemed to be the best way to express
what we needed to express.  This DTD is *not* meant to be used in
any specific way (e.g., in an implementation), it was merely the most 
convenient expositional tool the editors had at their immediate disposal.

It appears to me there are four logical choices:

1.  leave it as an SGML DTD,
2.  convert it to an XML DTD and lose useful information,
3.  use something other than an XML or SGML DTD,
4.  just delete the whole thing from the spec.

I don't know what the editors will decide to do.
(My preference is option 1, but I'm only one voice.)
