Mike provided me with a clear description of these values' meanings. I think these definitions ought to be included in the RFC 2910 update (2910bis). Here's the explanation Mike provided:</div><div class=""><br class=""></div><div class=""><blockquote type="cite" class=""><span style="font-family: Courier; font-size: 12px;" class="">"unknown" means (semantically) there is a physical/intrinsic value (location, level, etc.) but the value is not currently known. "no-value" means there is no (configured) value.</span><br style="font-family: Courier; font-size: 12px;" class=""></blockquote></div><div class=""><br class=""></div><div class="">Here are 2 possible places where I think it might be inserted:</div><div class=""><br class=""></div><div class=""><blockquote type="cite" style="font-family: Courier; font-size: 12px;" class=""> Table 3: Out of Band Values<br class=""><< INSERT EXPLANATION HERE >><br class=""> Table 4 specifies the integer values for the "value-tag" field:<br class=""><br class=""><br class=""></blockquote><br style="font-family: Courier; font-size: 12px;" class=""><br style="font-family: Courier; font-size: 12px;" class=""><span style="font-family: Courier; font-size: 12px;" class="">or here:</span><br style="font-family: Courier; font-size: 12px;" class=""><br style="font-family: Courier; font-size: 12px;" class=""><blockquote type="cite" style="font-family: Courier; font-size: 12px;" class=""> Note: An attribute value always has a type, which is explicitly<br class=""> specified by its tag; one such tag value is "nameWithoutLanguage".<br class=""> An attribute's name has an implicit type, which is keyword.<br class=""><br class=""><< INSERT EXPLANATION HERE >><br class=""><br class=""> The values 0x60-0xFF are reserved for future type definitions in<br class=""> standards track documents.<br class=""><br class=""></blockquote></div><div class=""><br class=""></div><div class="">Any objections?</div><div class=""><br class=""><div class="">
