asterisk users - May 2022 - Asterisk PJSIP pidf+xml presence question

We have a customer where their switch sends pidf+xml presence information in the
SIP INVITE message.

Does Asterisk process this pidf+xml information?
Does it store this in a channel variable that a dial plan could access?
If not, does it store present this information to AMI/ARI applications in any
way?

At Astricon 2019, one of the presenters talking about Presence and the growing
requirements for 911.  Needing to know not just building, but where (floor, etc)
in building.
I don't recall the full presentation, but I'm guessing pidf is what he
was referring to.

This is not currently supported. It is ignored if present in the INVITE,
and can't be accessed anywhere. You also can't send it. Support for
geolocation/E911 is being worked on.
