I wrote the patch for it. It's in Zope since 2.1.0b2. It basically
brings the dtml-try tag up to par with the python try statement.

You can do:

  <dtml-try>
    Tricky code here.
  <dtml-except>
    Exception handler here.
  <dtml-else>
    No exception occurred, rejoice.
  </dtml-try>

And you can also use finally:

  <dtml-try>
    Tricky code here.
  <dtml-finally>
    Cleanup. Always called, but you can't display anything, because an
    exception occurred.
  </dtml-try>
