Yes, sorry.

I was thinking the @class value would be unmodified, for the same reason
<task> can't be renamed to <general-task>.

Really I'm just trying to find a way that I can support anything other than
not doing anything to the status quo.

Personally, I don't think the concerns about surprise are sufficiently
compelling to require us to do anything more than providing the constraint
module and task.dtd that we already have. I just don't see how anything we
do will make things any better for the relatively small number of users who
might see a problem from their tasks suddenly becoming less constrained. The
migration fix is easy to implement (just include the same constraint module
used by the TC-provided task.dtd) and no documents are harmed by the change.

I would think they would go away: gone is gone and if we remove task.mod we
should remove any version-independent or version 1.2 catalog entries for it.

Alternatively, the entries could point to a
"this-module-has-been-deleted.mod" file, just to make the point clear.
