Really? I'd expect the old DTDs to stay around pretty much forever.
The point of versioning these things is you can keep the old ones around
to not break existing documents, and introduce changes in new versions.
If you went around deleting old DTD versions you'd break old documents
for no reason.
I recall a number of patches to settle on 4.3. A developer had 4.1 and 4.3 installed <BR>
but not 4.2, which was the requested version of the xsl in the doc.<BR>
So it did not work. I don't recall the exact numbers. The net of it is there is no way<BR>
to be sure of what gets shipped. Also, unless I misunderstood the docbook web site,<BR>
v5 is not compatible with v4, a migration is required.<BR>
