That's not true.  Darcs has tags, as Alistair has already pointed out,
and a darcs tag uniquely identifies a particular version of the
repository, just like a CVS tag does.

The difference is that unlike in CVS, the notion of file versions is a
derived concept rather than a fundamental one.  There's a duality
between versions and patches, in the sense that if you have one, you can
derive the other.  A darcs tag is a name that you give to a set of
patches; but by applying that set of patches and no others (by doing
darcs get --tag=tagname for example), you end up with files that are
identical to those that were in the repository at the moment it was
tagged.
