Who is lawyering now? The point of the exercise is to route the call based
on the location of the device. When the proxy sends the LI (not the LO) to
LoST, it knows it's the location of a device (it has the LO). The LoST
server may not know what it is, of course.

Yes it is, it's the LI of the device. That is the definition of LI, LO
without identification. The proxy knows it is doing this.

But that is not what 4119 says. It says LI or LO. It is quite specific
about it. I can understand arguing to change that language. I don't
understand arguing that it doesn't apply.

Isn't this something roughly like removing the author's name and copyright
on a document, and then publishing it?

Once you remove the identity AND THE RULESET from a PIDF-LO, you can do
anything you want with it, isn't that what you are saying?

I do understand the point you are making: without identity (and ruleset) a
location is not private, it's just like having a map and finding a place on
the map. I don't think you can so easily say if I remove the identity and
ruleset from a location I can do anything I want with it.

Let me cite an example. Suppose the LI had interior room information in it,
information not generally known by the public. Do you attach ANY privacy
concerns to that? Your argument is no, once I take the identity and ruleset
out, I can treat it as completely public information. I think that is
