Using element's value to govern minOccurs/maxOccurs of another

[Stretchwickster]

Is it possible to use an element's value to determine the minOccurs/maxOccurs of another? For example, if numSection (shown in the code below) equalled 3, then there would be a sequence of exactly 4 x,y coordinates.

<xsd:element name="numSection">
 <xsd:simpleType>
  <xsd:restriction base="xsd:positiveInteger">
   <xsd:minInclusive value="1"/>
   <xsd:maxInclusive value="50"/>
  </xsd:restriction>
 </xsd:simpleType>
</xsd:element>
[b]<xsd:sequence minOccurs=numSection+1 maxOccurs=numSection+1>[/b]
 <xsd:element name="x" type="xsd:float"/>
 <xsd:element name="y" type="xsd:float"/>
</xsd:sequence>

Your help would be much appreciated!

I don't think this kind of thing is possible.

Once again, thanks anyway.
