[Bob Jolliffe <bobjolliffe@xxxxxxxxx>]

Sorry I don't have much idea on how the detailed discussion has been on
actually implementing the attributes.  I had assumed (now it seems wrongly)
that you would use something based on our existing attributes mechanism.
 Having yet-another-object-with-attributes seems to me like the wrong
approach.  Either try to use existing mechanism or generalize and improve
that if there are deficiencies.  For example liked the discussion I was
hearing about labels etc.

Anyway too late here now I must sleep.  Catch up later.
