- X.521 uses the OBJECT-CLASS macro, an example is:
-
- person OBJECT-CLASS
- SUBCLASS OF top
- MUST CONTAIN {
- commonName,
- surname}
- MAY CONTAIN {
- description,
- seeAlso,
- telephoneNumber,
- userPassword}
- ::= {objectClass 6}
-
- Question: Is it possible, with this representation, to represent
- DEFAULT attributes, i.e. attributes which need not be included
- in the object, but which always must have a value, and where
- a default value, defined somewhere (where??) is used if the
- are not explicitly stored in the object.
-
- If not: How should the notation be extended to be able to
- handle DEFAULTed attributes?
