My interpretation of the spec is that "cannotDisseminateFormat" would be
illegal, since the "mandatory" status of oai_dc means that you MUST be
able to disseminate oai_dc metadata for every item.

I also think it would be wrong to return "noRecordsMatch", because in
fact the item does exist (since it can be disseminated in marcxml). IMHO
the correct approach is to return some oai_dc. NB the oai_dc schema has
no mandatory child elements inside the "dc" element, though for the sake
of form it would probably not be hard to generate a dc:title and a
dc:identifier from the marcxml store.
