Reported by matthew.horridge, Apr 18, 2007

The schema describes datatype restrictions as follows

   <xsd:element name="DatatypeRestriction">
     <xsd:complexType>
       <xsd:sequence>
         <xsd:element ref="owl11xml:Datatype"/>
         <xsd:element ref="owl11xml:Constant"/>
       </xsd:sequence>
       <xsd:attributeGroup ref="xml:specialAttrs"/>
     </xsd:complexType>
   </xsd:element>

There is no way to specify which facet is being restricted.

Since it looks like multiple facet restrictions per restricted datatype will be allowed [1] I suggest 
that we have a syntax that has a datatype facet restriction element, so that we have something 
which looks something like this:

                    <DatatypeRestriction>
                        <Datatype URI="&xsd;nonNegativeInteger"/>
                        <DatatypeFacetRestriction facet="&owl11;minInclusive">
                            <Constant Datatype="&xsd;int">10</Constant>
                        </DatatypeFacetRestriction>
                    </DatatypeRestriction>
                   
Cheers,

Matthew
