Dear William, 

Your file looks like this:

<?xml version="1.0" ?> 
<META xmlns="http://www.w3.org/2002/01/P3Pv1">
    <POLICY-REF about="http://www.qtrnote.com/w3c/policy.xml">
       <COOKIE-INCLUDE name="*" value="*" domain="*" path="*"/>

1/ the <?xml version="1.0" ?> directs the validator to the pure 
XML namespace, not to P3P ;)
Remove <?xml version="1.0" ?>

2/ in the about=, you don't need a full path, as the policy 
is on the same machine

3/ The notion of path in P3P is according to RFC 2396. This 
means don't use \, but use / instead

4/ your cookie include is kind of dangerous, as it would apply 
your policy on everything the cookie is replayed to. You should 
really limit this at least with the domain.

According to this, your p3p.xml should look like this:
<META xmlns="http://www.w3.org/2002/01/P3Pv1">
    <POLICY-REF about="/w3c/policy.xml">
       <COOKIE-INCLUDE name="*" value="*" domain="*.qtrnote.com" path="*"/>

Now the validator should be happy..
