<br><font size=2 face="sans-serif">Three questions to be considered</font>
<br>
<br><font size=2 face="sans-serif">1. In use, it seems what we really wanted
to convey is "surface characteristics". By labeling the element
"coating" and including the value "none", there is
an implication that coating is necessary and it leaves NO WAY to represent
surface characteristics of a NON-COATED media. For example, in paper, it
is possible to achieve a high gloss via high pressure calendaring (no coating...
but results in shiny surface". IS IT ACCEPTED PROPER INTERPRETATION
TO USE MediaCoatingWKV to mean media surface characteristics, in general,
coated or not? </font>
<br><font size=2 face="sans-serif">2. If the answer to 1 is YES, then what
is the semantic of the value NONE?</font>
<br><font size=2 face="sans-serif">3. What is the accurate and preferred
way to reference this "dictionary" in another document. Is it
more proper to reference 5100.3-2001(The IPP extension which originally
documented these values) or 5105.1 the Semantic Model, or point directly
to MediaWellKnownValues.xsd? I assume SM is preferred. </font>
<br>
<br><font size=2 face="sans-serif">Sorry for the double post. I think this
is broader than just an IPP question but the root document is an IPP extension.
