    In the IPP Production Print Attributes - Set 1,
    ftp://ftp.pwg.org/pub/pwg/candidates/cs-ippprodprint10-20010212-5100.3.pdf
    Page 47, 3.13.10 we describe Job Template attributes which augment the IPP
    media definitions including "media-front-coating" and
    "media-back-coating".
    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.
