Vince and all,
I think "location" in AVAIL_SPECTRUM_REQ may be the location of Slave
device when the request is made by the Master device on behalf of a
slave device.
See following in RFC6953
5.3. Operational Requirements
O.5 A master device MUST be able to query the database for the
available spectrum on behalf of a slave device at a specified
location before the slave device starts radio transmission in
white space at that location.
6. Security Considerations
PAWS is a protocol whereby a master device requests a schedule of
available spectrum at its location (or the location of its slave
devices) before it (or they) can operate using those frequencies.

How about the following wording?
Slave Device: A device that uses a Master Device to query a Spectrum
Database on its behalf to find available spectrum. The slave device
may or may not have geo-location capability. A slave device that does
not have geo-location capability MUST get available spectrum via a
Master Device.

I prefer to send independent replies on each topic, as that
way a given email thread is about a single topic (more or less).

1. Section 2.2 states Slave device as a device without
geolocation capability. I think the phrasing there need to be
different. A Slave device may or may not have geolocation
capability, but does not directly query the database. Also a
mobile Slave device, can it not switch as master device in adhoc?

I agree with the nature of his comment: a Slave device may
well have geolocation capabilities; however PAWS does not
expect it needs to use them to communicate with a Master
device. I would support an update to the definition of Slave.
