Hmm.  That wasn't my code.  I'd suggest instead (untested, but I've
used similar code in my own products):

<dtml-in "Catalog(meta_type="Folder")" size=1>
  There are <dtml-var sequence-length> items of type Folder.
</dtml-in>

I'm not sure what the relative advantages of these two code
snippets would be, but the latter does stick purely to dtml.
