[mapserver-users] [EXTERNAL] Re: Mapserver 7+oracle - wfs getFeature with filter on numeric field

[Eichner, Andreas - SID]

But the original post was about a WFS filter and it's schema defines the <Literal> element very loosely as

   <xsd:element name="Literal" type="ogc:LiteralType" substitutionGroup="ogc:expression"/>
   <xsd:complexType name="LiteralType">
      <xsd:complexContent mixed="true">
         <xsd:extension base="ogc:ExpressionType">
            <xsd:sequence>
               <xsd:any minOccurs="0"/>
            </xsd:sequence>
         </xsd:extension>
      </xsd:complexContent>
   </xsd:complexType>

And the implementation specification is also very imprecise about it:

  "The <Literal> element is used to encode literal scalar and geometric values."

So the schema does not restrict the <Literal>'s value to be xsd:double nor does the spec. FES 2.0 adds a "type" attribute and uses a XML schema datatype as example. Therefore I guess it's intended that a <Literal> element holds content matching the datatype advertised by a DescribeFeatureType request.
