I suspect that you suspect easily... let me know if I cant ask questions
about things I dont understand (be sure I looked for answers before
asking on the list).

** example:
diffServTBParamSimpleTokenBucket OID = mib-2.97.3.1
this OID has a meaning in the MIB tree, but it has not in the PIB tree. 
it seems that it's just a pointer towards the MIB and I was wondering
about the conssistency with the PIB namespace.

thank you Kwok for your explanations
