Re: [Ecrit] Additional text - location mech - wireless & mobilitysupport

["Roger Marshall" <RMarshall at telecomsys.com>]

Barbara:

I acknowledge the wording problem (and the bigger deployment problem).

How about just shortening the sentence a little by removing the
offending word, "respectively"... as follows:

" Requirements for 
endpoint location determination vary, depending on whether an 
endpoint's resulting location is based on internal 
(device-based) or external (network-based) measurements, or 
by manual provisioning, for mobile capable or fixed 
environment endpoints.  "

-roger.
