No, I've even written my own one (a BibTeX marshaller in
CMFBibliography to support drag-and-drop of BibTeX files
into Plone; but that's somewhat more involved as it has to
deal with flat representations of collections)

I'm very much interested in seeing this integrated. So far,
this limitation (that there is only one marshaller per schema)
has forced me to provide my own import/export handling including
UI.
