Thanks for clearing this up for me :-)

So I guess the real question is what compound types (if any) do we think
will be of benefit to the community and therefore included in the usage
name-space? i.e., should we make an effort to try and define
GridUsageRecord or AggregateUsageRecord now we have some foundation for it?

If this is useful then how best do we progress this as a group?
