User Guidelines
• The parameters refclassname and class-map-name can not be the same.
• Only one other class may be referenced by a class.
• Class maps may be chained, for example, a class-map may reference
another class map, which references a third class map, et. seq.
• Any attempts to delete the refclassname class while the class is still
referenced by any class-map-name fails.
• The combined match criteria of class-map-name and refclassname must
be an allowed combination based on the class type.
• Any subsequent changes to the refclassname class match criteria must
maintain this validity, or the change attempt fails.
