By previous agreement. (E.g., after renting an entire transponder 
exclusively for ULE packets.)
What I'm trying to say is that the ULE encapsulation is not dependent 
on the DVB/ATSC magic around it doing its thing (or, more precisely, is 
only dependent on it if that magic is in actual use by some component 
on the way).  So it would be a mistake for ULE to stipulate that those 
tables are maintained properly.
Or, in other words, if the DVB/ATSC magic is required to properly 
transport the ULE packets, this is not a conformance requirement on the 
ULE packets, but on the system that injects them into the DVB/ATSC 
world.
