optional...

This is only needed if required and it's required that the length
is >= 1.  I'm not a fan of other, especially if it's an open vocab..

I think adding it across the board is fine...  It makes handling the
TLO's easier, and more consistent, and I can see most of the TLO's
using them...  I don't have a strong preference though...

> b.       Allan also suggested that if we don’t add it across all top-level objects, it should be added to Campaign. Are there other TLOs that we should add it to, even if we don’t add it across all of them?
