Abstract Abstract
The Incident Object Description Exchange Format [IODEF] provides a The Incident Object Description Exchange Format [IODEF] provides a
Reference class used to reference external entities (such as Reference class used to reference external entities (such as
enumeration identifiers). However, the method of external entity enumeration identifiers). However, the method of external entity
identification has been left unstructured. This document describes a identification has been left unstructured. This document describes a
method to provide structure for referencing external entities for the method to provide structure for referencing external entities for the
[IODEF] Reference class. [IODEF] Reference class.

Per [IODEF] the ReferenceName is of type ML_STRING. This becomes Per [IODEF] the ReferenceName is of type ML_STRING. This becomes
problematic when specific references, especially enumerations such as problematic when specific references, especially enumerations such as
[CVE], [CCE], [CPE] and so on, are referenced - how is an implementer [CVE], [CCE], [CPE] and so on, are referenced - how is an implementer
to know which type of reference this is, and thus how to parse it? to know which type of reference this is, and thus how to parse it?
One solution, presented here, is to require that ReferenceName follow One solution, presented here, is to require that ReferenceName follow
a particular format. a particular format.

The Reference Name Format uses XML to provide the structure for The Reference Name Format uses XML to provide the structure for
enumeration identification, and requries that a specific Abbreviation enumeration identification, and requires that a specific Abbreviation
