yaw, pitch and roll ? and position accuracy?

Very sorry to jump in so late in the dialog. ( i've been buried elsewhere)

But, I have a couple of quick questions about the core data model:

Besides latitude, longitude and altitude attributes of position, What 
has been decided about yaw, pitch and roll?

Can someone tell me if i'm correct in  assuming that the nominal CRS 
would allow for a designation of the accuracy of the position. ( I"m 
seeing the emergence of use cases requiring millimeter accurate positioning)

Many thanks,

Mike Liebhold
