Can you elaborate on the work and confusion?   Here's the whole set of 
text that would be removed:

     The 'opaquelocktoken' URI scheme extends the UUID mechanism slightly
       while still guaranteeing the lock token to be unique across all
    resources for all time.  With the 'opaquelocktoken' scheme, the 
server MAY
    reuse a UUID with extension characters added.  If the server does 
this then
       the algorithm generating the extensions MUST guarantee that the 
    extension will never be used twice with the associated UUID.

    OpaqueLockToken-URI = "opaquelocktoken:" UUID [Extension]  ; The
    UUID production is the string representation of a UUID. Note
       that white space (LWS) is not allowed between
    elements of this production.

Removing that text doesn't stop server implementors from using 
"opaquelocktoken" or make them non-compliant if they continue to use 
it.  I still recommend removing it now that we have the "urn:uuid:" 
namespace to recommend instead.
