"SPARQL 1.1 Service Description" from Fuseki?

[Bob DuCharme]

http://www.w3.org/TR/2012/PR-sparql11-service-description-20121108/#accessing 
describes how "SPARQL services made available via the SPARQL 
Protocol/should/return a service description document at the service 
endpoint when dereferenced using the HTTP GET operation without any 
query parameter strings provided." While using jena-fuseki-0.2.5, the 
following query to Fuseki's endpoint does work for me, so I know that 
things are set up correctly:

   curl 
"http://localhost:3030/myDataset/query?query=SELECT%20DISTINCT%20%3Fp%20WHERE%20%7B%20%3Fs%20%3Fp%20%3Fo%20%7D";

However, the following gets me a 404:

  curl "http://localhost:3030/myDataset/query";

Am I doing something wrong, or has this not yet been implemented in 
Fuseki? Can anyone tell me of other endpoints that have implemented the 
service description spec?

thanks,

Bob
