TITLE: Ontology versioning

The Requirements Document states that ontology evolution is an important
design goal and that versioning information is a requirement for OWL.
However, DAML+OIL has very limitied support for versioning information.
It only has a tag called "daml:versionInfo" which contains an
unstructured string. To support machine processing, OWL needs explict
structured information related to versions, such as capabilities to
point to prior versions, specify backward-compatibility, and to
deprecate terms (i.e., state that they are available for
backwards-compatibility only).
