RE Loretta, and Roberto and John et al on guidelines, user agents and "until
user agents"


I think the concept we have been missing here is "Safe Harbor".  

Techniques do not define what is needed for conformance.  Rather they state
was are known and accepted ways for meeting Success Criteria.   If you
follow them you are following accepted practice and should be in a "safe"
position if someone questions you.  (a manager, a user, a procurement
officer or a court for example)

You can use other means - but then you may have to justify or prove that
your method is good enough when challenged.   Easier to use what is accepted
but not necessary.  

What is generally accepted will change over time - as do the user agents.
So will the techniques doc.  But if we write the guideline right - they will
last longer before needed tweaking. 

At least this is where our discussions have been leading my thinking lately.
