OTOH we need some clever way to build up forms from more than one
Schema.

at the DZUG-Sprint we worked on NewsItem/Site ContentTypes and we wanted
to be able to present the user a from that uses the content's fields and
some DublinCore Fields to be edited in one step.

We ended up in writing an adapter that subclassed from
ZDAnnotatableAdapter and extended it with some properties that store the
content-objects data in context.

Tres made it possible to use adapters for add/editforms but the
app/form/utility methods don't care about that so we had trouble to
stay in the right context (e.g. zmi_views were not displayed, because
we needed to make the context of that form the adapter)

the ability of grouping fields from 1 or more schemata to build 
add/edit-forms would really rock.

so go for it :)
