RDF and uuid. why is there no urn scheme?

<rdf:Description about='uuid:8949dbc6-31ad-11d9-9c7d-d112c21f7031'>

Why about

doesn't this one contain urn:uuid:8949dbc6-31ad-11d9-9c7d-d112c21f7031

instead? Isn't uuid an urn, and therefore it is required to have an urn diagram in front of you:

Following the specification chain, the IANA URN registry does indeed register 'uuid' as a namespace after 'urn:'. So yes, the above url is not correct and it should start "urn: uuid" as you would expect.

This URI is wrong. Using the following RDF document in W3C RDF Validator returns an error

<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
