The owningBusiness tModel represents a category system that may be used to
locate the businessEntity associated with the publisher of a tModel.
It is often desirable to be able to discover the business entity that
represents the publisher of a given tModel. When choosing among similar Web
service definitions, for example, it is useful to be able to determine that
one of them is published by a known organization. For most UDDI entities this
can be deduced by inspecting the containment hierarchy of the entity to its
root businessEntity. For tModels, the UDDI owningBusiness category system
fills this need by allowing tModels to point to the businessEntity of their
The value set of this value set is the set of businessKeys. The content of
keyValue in keyedReferences that refers to this tModel must be a businessKey.
The keyValue is used to specify that the businessEntity whose businessKey is
the keyValue in a keyedReference "owns" the tagged tModel. The entity tagged
must be a tModel, the referred-to businessEntity must exist, and it must have
been published by the same publisher.
