To facilitate searching UDDI registries for RDDL documents, I created a 
"taxonomy" tModel [1] in the public UDDI Business Registry (UBR).  It is 
"unchecked" meaning the the UBR will not check the value  of the keyValue 
attribute when people publish to UBR.  (Private UDDI registries could make 
it a checked taxonomy so the registry would not allow invalid keyValues).

The intent is to allow only one valid value:  keyValue="rddlSpec".

It is to be used like keyValue="wsdlSpec" in UDDI, which in accordance with 
UDDI best practices [2], is used to help discover WSDL files.

An example [3], is a tModel that points to a RDDL document in the 
overviewURL.  It contains a categoryBag that uses [1].

I can then discover RDDL files (which have been registered in the UDDI 
registry) using

<find_tModel xmlns="urn:uddi-org:api_v2"  generic="2.0">
         <categoryBag>
                 <keyedReference 
tModelKey="UUID:49BE0F40-E9F9-11D7-B602-000629DC0A53" keyValue="rddlSpec"/>
         </categoryBag>
</find_tModel>
