'top' is the root of the object class inheritance tree and as such
all other classes inherit it sets of allowed and required attributes.
Specifically, 'top' requires 'objectclass' and hence ensures that
all entries include a list of applicable object classes.
For more details on the LDAP/X.500 information model, I
suggest reviewing Chadwick "Understanding X.500" <http://www.salford.ac.uk/its024/Version.Web/Contents.htm>.

Yes. The organization object class does not allow the dc
(domain component) attribute type. The dcObject auxiliary
object class is used to allow the inclusion of the type.
