Revising attribute type 'mail'?

HI!

Given that RFC 5336 and RFC 5337 are out now the question arises whether

1. attribute type 'mail' defined in RFC 4524 should be revised to use
LDAP syntax DirectoryString instead of IA5String with a new OID but the
same NAME 'mail'

or

2. a new attribute type should be defined with a different NAME.

Personally I tend to 1.

Ciao, Michael.
