To ensure that one can delete by value any and all values
added by value.  That is, if one can do:
        changetype: modify
        add: cn
        cn: X

one should be able to:
        changetype: modify
        delete: cn
        cn: X

and have the latter X match the former X.

Even though introduction of LDAPprep made apparent the need for
this, this is not just about LDAPprep,   It's about any rule where
there is any X where R(X,X) is Undefined.
