I have considerable sympathy for what you are pointing out.

Firstly, the TAG document isn't done.  The TAG internal consensus puts it at
around 20-40% done.  Further, it hasn't gone through the consensus process -
AC review, Last Call, etc.

Secondly, I completely agree with providing justification for any particular
constraints that are held to or not.  This is why in the latest TAG document
you are starting to see the difference between constraints and properties.
The whole point of constraints is to meet certain properties.  IMHO, the
ws-arch still has considerable distance to travel on really getting to the
heart of what properties it's trying to meet.  But we're making good
progress towards that end.

I think we have to cover all the properties and derived constraints.  Then
we may give various levels of treatment to the rationale for this, and
certainly would cover controversial ones in more detail.

My $.02 worth.
