I have a section of a schema below and I've got a problem I can'y
figure out. I'm not having a good day though so it's probably just me
being stupid!!
I need the shearStrength element to have an xink:href attribute as
shown below but I also need it to have something like:

<extension base="float">
<attributeGroup ref="ags:UoMGroup" />
</extension>

ie. i need to restrict the value of shearStrength to a float value and
associate it with an attributeGroup I already have, as well as
including the xlink:href attribute.


<element name="layerMaterialParameters">
<complexType>
<sequence>
<element name="shearStrength">
<complexType>
<attribute ref="xlink:href" use="required"/>
</complexType>
</element>
<!-- other elements here -->
</sequence>
</complexType>
</element>



Any help would be much appreciated!

Could it be this ?

<xs:element name="shearStrength">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:float">
<xs:attribute ref="xlink:href" use="required"/>
<xs:attributeGroup ref="ags:UoMGroup"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>

I'm still learnig about namespaces so I tested it without namespaces.
it's not enough, I now

Yeah, after messing around in XMLSpy, I came up with that solution too.


But somehow it doesn't seem that logical though (assuming it's right!)
having both the attribut and the attribute group which are unrelated
within the same 'float' extension?!
Ah well!
