These are likewise reflected in the PWG Semantic Model v1.0 MediaWellKnownValues.xsd as "MediaCoatingWKV".         </xsd:simpleType>         <xsd:simpleType name="MediaCoatingWKV">                 <xsd:restriction base="xsd:NMTOKEN">                         <xsd:maxLength value="255"/>                         <xsd:enumeration value="none"/>                         <xsd:enumeration value="glossy"/>                         <xsd:enumeration value="high-gloss"/>                         <xsd:enumeration value="semi-gloss"/>                         <xsd:enumeration value="satin"/>                         <xsd:enumeration value="matte"/>                 </xsd:restriction>         </xsd:simpleType> Three questions to be considered 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? 2. If the answer to 1 is YES, then what is the semantic of the value NONE? 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.   Sorry for the double post. I think this is broader than just an IPP question but the root document is an IPP extension. ---------------------------------------------- Harry Lewis IBM STSM Chairman - IEEE-ISTO Printer Working Group http://www.pwg.org IBM Printing Systems http://www.ibm.com/printers 303-924-5337 ---------------------------------------------- </BLOCKQUOTE></BODY></HTML>
