No. Only top-level bases should be managed by XMANAGER.

There are no restrictions as to which widgets can be group
leaders for other widgets. When the group leader dies (even
if it is not a top-level base), the members of the group
die as well. Group leaders are *normally* top-level bases,
since it is odd to be killing off widget sub-hierarchies.
In fact, I would suggest you better have a VERY good reason
for doing so, or you are likely to get into some kind of
trouble. :-)
Cheers,
