Class Hierarchies
This appendix provides diagrams of the hierarchies of object classes. The four main
figures show the root objects: message, probe, report, and P1-encoded object. Due to
the complexity of the class structures, some subobjects are shown in separate figures.
When reading the diagrams, be aware of the following conventions:
•
The DDL names of object classes and attribute types are replaced with simplified
names for readability. For example, MH-T-CONTENT-TYPE is replaced with
Content type.
•
The names of multivalued attributes are italicized: for example, Recipient
descriptors.
•
If the syntax of an attribute is OM-S-OBJECT, indicating that its value is an object,
the attribute type appears in plain (or italic) type and the object name appears in
bold type enclosed in parentheses: for example, Expansion history ( Expansion
record ).
•
The symbol o (a lowercase letter O) preceding an attribute indicates that the
attribute is optional.
