I noticed the following:

Modified text in section 4.2:
"If no Geolocation-Routing header field is present in a SIP request, 
   a SIP intermediary MAY insert this header. Without knowledge from a 
   Rulemaker, the SIP intermediary inserting this header-value SHOULD 
   NOT set the value to "yes", as this could allow the Target's 
   location to be forwarded to third parties without the Target's 
   explicit permission. An easy way around this is to have the Target 
   always insert this header-value as "no"."
Even if the value is set to "no", the target's location could end up being forwarded to third parties without the target's explicit permission. Normal SIP routing (without taking location into account) can result in a request being forwarded to another destination. So the words:
"as this could allow the Target's 
   location to be forwarded to third parties without the Target's 
   explicit permission"
should be deleted, as this can arise anyway and is not impacted by the value of the Geolocation-Routing header field.
