That's odd, XclExpFmlaCompImpl::AppendTrailingParam() is called in
XclExpFmlaCompImpl::FinishFunction() that should be called also for
OOXML export (or was it?). Best to place a breakpoint there and see
if/when it gets hit.

BUT, I think I might know why it doesn't get called anymore ... the
OOXML formula string is now directly generated from the token array,
which bypasses all mechanisms we had in place for the Excel binary
export and the earlier OOXML export benefitted from. It may be we have
to re-implement that entirely :-(  and end up with an almost duplicated
functionality..

Would make sense to add those similar to the existing ones.
