On the availability of DTDs online:

(1) A number of DTDs developed by the Text Encoding Initiative (TEI) are
available on the BITNET listserver at uicvm.bitnet.   For a full title list,
send mail or interactive message to listserv@uicvm.bitnet (or
listserv@uicvm.uic.edu) with the first line INDEX TEI-L.  (You may have
to first subscribe to the TEI-L discussion list with the command
SUB TEI-L YOUR_NAME).  Order the DTDs with the command GET FILENAME FILETYPE.

(2) Some CALS-related DTDs are available on Internet durer.cme.nist.gov
(129.6.32.4), along with a lot of other CALS standards documents,
hypertext browsing software for reading the MIL standards, etc.
