I'm concerned that the following two notions may be inconsistent:

a) WS-Names should be globally unique (Andrew)

b) The WS-Name can be used to pass a LSF jobid (Chris)

Or is Chris proposing that LSF be changed to generate its jobids with
whatever scheme WS-Naming proposes to ensure global uniqueness? (If it
doesn't, then I don't think that Chris can guarantee that the names that
LSF generates and the names that someone else generates will not
collide.)
