Because it's easier to find stuff by working from the TableName; there's
much less ASN.1 understanding required and my ASN.1 is ofttimes weak.

Also, it lets the <foo>.ok state dump have a label indicating namespace
so I don't need to worry about globally unique names, only relatively
unique.  (Does ASN.1 actually require global uniqueness?)

So I have an mrtg.ok which contains:
community at netapp1a-mgmt   dfTable.dfFileSys       /vol/mail/	5

Are these guaranteed to use the same indexing?

If so, then yes my patch imposes too tight a constraint.  :^(
