Don, I see no problems with that. One convention that PINES came up with (or inherited from their previous system) was to combine the system shortname with the branch shortname to expose a bit of the hierarchy at a glance when looking at a specific lib, and to reduce the chance of collision with shortnames.
So for example, you may want to consider: ASLAN -> ATS ->-> ATS-BLF ->->-> ATS-BLF-SA ->->-> ATS-BLF-BL ->-> ATS-MDD -> AUL ->-> AUL-DFK ->->-> AUL-DFK-UA ->-> AUL-AUF -- Jason
