[IPP] [PWG5100.20] Issue #36: No test for "LOC" DNS records mandated by 5100.14 section 4.2.2

[Issue Unconfirmed]

PWG 5100.14 section 4.2.2 requires Printer objects to publish LOC records
for their service.  But 5100.20 lacks a requirement to test for them. 
(Should we eliminate them from 5100.14 or make them optional?)
