A short explanation: sql queries return a result object (so does ZCatalog
btw), which you can't address directly in DTML (or at least I wouldn't know
how ;-)  If it the result object is empty it won't have a (sequence) start
in a dtml-in. This is the same code SearchInterfaces uses for returning a
'this query has no results'.
