Question on current version of the geolocation spec

When looking through the proposed recommendation, I was puzzled by the 
fact that section 4.2 is normative. Since all the requirements to 4.2 
apply to the *recipient* of the geolocation information, and not to the 
implementation, doesn't this make it impossible for any vendor to 
produce a conformant implementation of the geolocation API in a browser 
(as they cannot assure that the resulting system will be in accordance 
with 4.2)?

I suspect that the section is really missing the 'This section is 
non-normative' label.
