We'll make a list as we go through the text, but the goal is to remove any
reference to emergency call.

We will rewrite this text to discuss the general issue of security in
location based routing while not having any specific text that is peculiar
to emergency calls.

We would then have in ecrit documents specific advise for emergency call use
of location conveyance.

I would prefer to rewrite this text to better work in generalized location
based routing, and then have minimal additional text in ecrit documents that
expand on that.

The "Querying for routing..." sentence can reasonably be rewritten in ecrit
documents.  The other two sentances in the cited text probably should remain
as general advice for any location based routing scenario.

Well, do you agree with the principal, while reserving the right to comment
on the specifics?
