OK.. how about one more little special case....
There are
<dtml-in "Catalog(meta_type="Folder")" size=1>
<dtml-var sequence-length>
<dtml-else>
0
</dtml-in>
items of type Folder.
untested of course. ;-)

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.
