<div class="WordSection1">
<p class="MsoNormal">Just checking my understanding…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Given the following RFC 8011 definition for 1setOf X attributes:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">5.1.18. ’1setOf X’<o:p></o:p></p>
<p class="MsoNormal">The ’1setOf X’ attribute syntax is one or more values of attribute<o:p></o:p></p>
<p class="MsoNormal">syntax type X. This syntax type is used for multi-valued attributes.<o:p></o:p></p>
<p class="MsoNormal">The syntax type is called ’1setOf’ rather than just ’setOf’ as a<o:p></o:p></p>
<p class="MsoNormal">reminder that <span style="background:yellow;mso-highlight:yellow">
the set of values MUST NOT be empty (i.e., a set of<o:p></o:p></span></p>
<p class="MsoNormal"><span style="background:yellow;mso-highlight:yellow">size 0).</span> Sets are normally unordered; however, each attribute<o:p></o:p></p>
<p class="MsoNormal">description of this type can specify that the values MUST be in a<o:p></o:p></p>
<p class="MsoNormal">certain order for that attribute.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">From 5.2.11:<o:p></o:p></p>
<p class="MsoNormal">"media-ready", which differs from "media-supported" in that legal values only<o:p></o:p></p>
<p class="MsoNormal">include the <span style="background:yellow;mso-highlight:yellow">
subset of "media-supported" values that are physically<o:p></o:p></span></p>
<p class="MsoNormal"><span style="background:yellow;mso-highlight:yellow">loaded and ready for printing with no Operator intervention required</span>.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If there is no media present in any trays of a printer, and media-ready attribute is not allowed to have 0 values, how is media-ready supposed to be show that there is no media ready in a Get-Printer-Attributes response? Should the Tag
Value (0x13) ‘no-value’ be used instead of (0x44) keyword? This somewhat implies a modification of the data type of media-ready from 1SetOf X to no-value? If this is so, then I also presume that for any out of band values, there is no value-length or value
appended to the encoding of Attribute-with-one-value (RFC 8010 Section 3.1.4).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">===========================<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also – another question I’ve always wondered but would like to verify:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The data type “1setOf (type2 keyword | name(MAX))” seems to imply that any attributes of this type can either be<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">1setOf(type2 keyword) only or<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">2setOf(name(MAX)) only<o:p></o:p></li></ol>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">And the set cannot have keyword and name values intermixed. Is that correct? The encoding document RFC 8010 Section 3.1.5 shows each additional value (after the 1<sup>st</sup> value) all have value-tags, so theoretically, an encoding
can have intermixed data types.<o:p></o:p></p>
<p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
