The Filter specification 1.0 states:
<xsd:element name="Intersects" type="ogc:BinarySpatialOpType"
substitutionGroup="ogc:spatialOps"/>
however filtercapabilties.xsd, referred by wfs 1.0 caps states:
<xsd:element name="Intersect">
<xsd:complexType/>
</xsd:element>
and Filter 1.1 states:
<xsd:element name="Intersects"
type="ogc:BinarySpatialOpType"
substitutionGroup="ogc:spatialOps"/>
while wfs 1.1 caps states:
<xsd:simpleType name="SpatialOperatorNameType">
<xsd:restriction base="xsd:string">
<xsd:enumeration value="BBOX"/>
<xsd:enumeration value="Equals"/>
<xsd:enumeration value="Disjoint"/>
<xsd:enumeration value="Intersects"/>
As far as I can see GeoServer respects all by the letter, even the
inconsistency in WFS 1.0/Filter 1.0 between the caps name and the
actual filter name.
