Here is the syntax that works:

<dtml-if "_.hasattr(PARENTS[-1].members, getUserName())">

Bill's suggestion put me on the right track, and a search
through the archives revealed the following posting from
Chris McDonough:

http://lists.zope.org/pipermail/zope/2000-April/024628.html

Which gave me the last piece of the puzzle. Just goes to
show you that all Zope Zen is contained within the archives
;-)

This should be useful for anyone who wants to implement a
portal where only *some* members have a home folder. The
current all-or-nothing approach of both the PTK and
membership seems limiting.
