revisions is not enough. Regardless, I would still like to see whatever

simple symbolic revisions.
    

When you say "lighter-weight", I'm not sure what you mean.  Creating a
tag in Subversion is a constant-time and constant-space operation,
regardless of the size of the tree being copied.  Placing a tag in
CVS, by comparison, places an entry in the repository for each file
being tagged.  So "cvs tag" takes both time and space proportional to
the size of the tree being tagged.  Subversion tags are much more
light-weight than CVS tags. 
  

I'm sorry Jim - I wasn't clear here. I didn't mean that the implementation wasn't light-weight in Subversion. You guys are wizards in that respect :) I only meant that from the user perspective, it should appear to be a simpler thing. But as I stated in an earlier response, tags are important enough, that they deserve to be treated as a first-class concept.
