Ah, you mean the \par message? This is related to the non existing i.e.
only living inside tex \endtemplate primitive and the message is one of
those originating deep inside tex when tex is not really able to determine
the problem (similar things happen with missing { or } messages when
v/halignments are used in the wrong v/h mode).
The problem is that commalist processing can be nested and has no grouping,
which means that the internal counters get confused when used inside
implicitly grouped situations like alignment cells. So, one way out is a
rather dirty trick:
\expanded{\globalprocesscommalist[\XMLDBElementList]}
i.e. use a special version of comma list processing
[BTW, i now have a version of bTABLE cum suis running which breaks across
pages and has auto-repeated headers, handy for xml too]
