That confirms my assumption that it is due to the change that formula
expressions are now written using the compiler internals.

There are already entry points that do something similar for the old
non-ODFF (aka PODF) OOo-XML format, i.e. in
FormulaCompiler::CreateStringFromTokenArray() and in
formula/source/core/api/token.cxx all functions with *Rewrite*()

The MissingConvention and FormulaMissingContext need to handle also the
OOXML cases, or probably better create a derived MissingConvention for
the OOXML case so there are less explicit comparisons and/or switch
cases to differentiate.

_Maybe_ that and the code in XclExpFmlaCompImpl::AppendTrailingParam()
could even be united in some way to diminish code duplication.

If you want to take a stab at this just tell me, otherwise I'll do.
A bug report might be good so things don't get lost.
