This is not clear from the definition.  The bit is defined as indicating
the LSP is a secondary (or protecting) LSP and in 1+1 protection the
secondary LSP may not be used for extra traffic.

Perhaps the problem here is that protection features are being defined
before the protection framework and requirements are done.  Is this
presupposing some particular outcome of the recovery work in CAMP?
