AOLserver doesn't have any xml capability.
I discussed with several people at the LinuxWorld show (Roberto and
Talli mainly) about writing a new export/import module
for acs and that would include xml (as xml is still far from the
standard exchange method) as well as csv, dif and etc.
I think a strict xml package is to specific and it should be folded
into a generic import/export package in the core or an aol C module.
