Implementation Guide

Does anyone know when this will be available?  I am putting together an
estimate on the effort required for our company to implement CAP.  Such
a guide would be quite useful.  

If it isn't available soon, I do have one question that keeps coming up
at our developer meeting, what is meant by required?  In other words,
can we send a NULL element <certainty> or must a value be provided?
Also, how important is the ability to link alerts?  At this time, most
of our alerts are information rather than warnings.  However, we as part
of a new partnership, we are becoming involved with geocoded warning
messages.

Finally, is there going to be a governing body that evaluates compliance
with the standard?  Thanks in advance!
