[Issue Unconfirmed]

Consensus from 2015-05-09 IPP WG conference call was to leave 5100.6 as it
is, but rather clarify 5100.14 can conditionally require it depending on
"multiple-document-jobs-supported" = 'true', since 5100.14 may define its
own normative requirements and doesn't need to simply adopt all 5100.6
normative requirements.
