Hi Chris:

Why do you use gml:_GeometricPrimtive since PYXISPoint is a point?  You
are saying it can do where ANY geometric primitive can go.  Is that
correct?  Why not make the substitution group just gml:Point?  Generally
one would strive to use the closest geometric type. Your substitution
should work - but I notice that the property is PointMember and not
pointMember in your example - remember XML is case sensitive.

Hi Folks.

Sorry to bother you, but I am stumped again.

I am attempting to do this.

<xsd:element name="PYXISPoint" type="PYXISPointType" abstract="false" 
substitutionGroup="gml:_GeometricPrimitive"/>
   <xsd:complexType name="PYXISPointType" abstract="false">
       <xsd:complexContent>
           <xsd:extension base="gml:PointType">
               <xsd:sequence>
                   <xsd:element name="Index" type="xsd:string"/>
               </xsd:sequence>
           </xsd:extension>
       </xsd:complexContent>
   </xsd:complexType>

At this point everything works fine and authenticates. What I am trying 
to do next is this.

<gml:MultiPoint>
<gml:PointMember>
<PYXISPoint>
BLAH
</PYXISPoint>
</gml:PointMember>
</gml:MultiPoint>

However what is confusing me is. I thought because I specified the 
Subsitition group, I could use a PYXISPoint anywhere a gml:Point was
used.

However if I do something like.
<gml:location>    <PYXISPoint>
 </PYXISPoint>
</gml:location>

This is ok.
Any suggestions ?

Cheers
Chris.
