[DFDL-WG] of check constraints and fixed

[Steve Hanson]

The checkConstraints() function will check against the XSDL fixed 
attribute. It won't check the XSDL default, minOccurs or maxOccurs 
attributes.

Check constraints can be used…
 
                        <xsd:annotation>
                                    <xsd:appinfo source="
http://www.ogf.org/dfdl/dfdl-1.0/">
                                                <dfdl:assert test="{ 
dfdl:checkConstraints(.) }" message="There cannot be more than 59 seconds 
in a minute."/>
                                    </xsd:appinfo>
                        </xsd:annotation>
 
…to validate (while parsing) the restrictions placed on an element:
 
                        <xsd:simpleType>
                                    <xsd:restriction base=
"xsd:unsignedInt">
                                                <xsd:maxInclusive value=
"59"/>
                                    </xsd:restriction>
                        </xsd:simpleType>
 
Is check constraints similarly required to validate the fixed value of an 
element while parsing?
 
<xsd:element name="MimeVersion" dfdl:initiator="MIME-Version:%SP;" 
dfdl:terminator="%NL;" type="xsd:string" dfdl:length="3" dfdl:lengthKind=
"explicit" fixed="1.0">
 
If not, then how do I force it to validate while parsing?
