<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">PWG 5100.3 section 3.13.2 documents keyword values for media-type. However, this list is incomplete for what our products need to report (for example, differentiation between photo-glossy vs. photo-matte,
recycled paper, heavy cardstock vs. light cardstock, pre-punched etc.)</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">RFC 8011 leads me to the IANA IPP registry, which leads me to PWG 5100.7, which leads me to PWG 5101.1, which leads me to a list that does not intersect with the list in PWG 5100.3.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The document makes reference to RFC2534 for a registry of other types. Where is this registry and how do I access it? Is this separate from the IANA IPP registry? And if the registered keywords are not
sufficient are we forced to implement all media-type-xxx as name(MAX) instead of type3 keyword?</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Going further, how does one go about registering new media-type keyword values?</span><o:p></o:p></p>
