referencing attribute types

Hi,

As we are going to restructure schemas and attribute types, I would 
suggest to adopt X.520 structure of attribute types. That is

- System attribute types

- Labelling attribute types

- Geographical attribute types

- Organizational attribute types

- Explanatory attribute types

- Postal Adressing attribute types

- Telecommunication attribute types

- Relational attribute types

- Domain attribute types

I propose to map following attribute type originating from X.520 to a 
ldap schema:

dnQualifier and organizationIdentifier.
