    This is an ORM concept inspired in Cayenne by the JPA spec (the term
    is taken from JPA as well).

    An embeddable is a reusable compound ObjAttribute type that maps to
    multiple DbAttributes. E.g. if you have "person" and "organization"
    tables, that both have address columns in them (address1, address2,
    city, etc.). You can create an embeddable "Address", and then use it
    in both Person and Organization entities as a single attribute, even
    though it maps to multiple columns.

    We do need a docs entry on that. Hopefully will catch up during beta.
