All,

I think this errata in essence is correct, though I would want to
propose a slight modification to the Corrected Text.

Slightly Corrected Text
--------------
If the "bandwidth protection desired" flag is set in SESSION_ATTRIBUTE, 
the PLR
SHOULD try to provide a bandwidth guarantee; if this is not feasible, 
the PLR
SHOULD then try to provide a backup without a guarantee of the full 
bandwidth.

Note 1: lowercase is how the document treat all othr names of flags in
flowing text.

Note 2: with this slight change I think this Errata could be verified
and held for a document update.
