OASIS has been using RDDL 2.0 for namespace documents [4].
W3C has been using RDDL 1.0 for namespace documents [5].
WADL also has a RDDL 1.0 namespace document. [5]

[4] and [5] are bookmarks of these examples.

I had proposed [6] using RDDL as a UDDI "taxonomy 
document" where the overviewURL of a UDDI tModel 
points to a RDDL document, which can then point 
to various artifacts associated with the 
taxonomy.  For example, if there is an OWL 
representation of the taxonomy, the RDDL document 
could point to it with an appropriate 
rddl:nature, or use a different rddl:nature to 
point to a different representation (e.g., one 
that can be imported into a Systinet UDDI 
registry).  My hope was that tools that deal with 
taxonomies could discover taxonomies registered 
in UDDI, then retrieve the RDDL, then retrieve 
the representation that the tool could import to 
work with the taxonomy locally.  I have been 
frustrated with the slow response time of some 
UDDI deployments that have round trips to the 
server every time I drill down a level of a 
taxonomy.  Having a local copy of all or part of 
a taxonomy would hopefully provide better 
response time and improve the usability of the 
taxonomy.  You probably won't find this idea for 
RDDL "being used in the wild" currently.
