I lump all the LSPP/MCS work and tightening the audit system with SE Linux as 
"LSPP" work. I don't want to mess with type enforcement until the message 
numbering is settled. That decision has the new operators as a pre-requisite. 
If new operators can't be done, then the way we filter these will have to be 
via a different mechanism.

Maybe not. Suppose they are doing large database system. They may decide to 
turn SE Linux off. We really cannot depend on that since they are free to 
boot with it on or off. This has to stand on its own.

Yes. Its not needed at all for CAPP.

MCS is virtually the same configuration as LSPP - just a simplified policy. 
But from our perspective in the audit system, it is LSPP. We need to have the 
labels in the audit messages.

Right now, I consider everything CAPP. The SE Linux messages I'm still mulling 
over their classification. They could arguably go either way. All new SE 
Linux messages for the support of MCS and LSPP would fall into the LSPP 
category.
