I get concerned about inherited properties where our typology and the external authorities typologies don't match.  My concern doesn't mean that it is improper.  A better match would be road-type residential && controller CoS for example if we're going to work inheritance regularly.

It also exposes problems like Collins Street residential being the terminator of the Epsom Road / Huntley St rat run; or Doody Street Tertiary versus Doody Street residential for no good reason.
