Re: xml schema question

Hi Rob,

That will be equivalent with
<xsd:complexType>
     <xsd:choice minOccurs='0' maxOccurs='unbounded'>
          <xsd:element ref='dd'/>
          <xsd:element ref='cc'/>
          <xsd:element ref='aa'/>
          <xsd:element ref='bb'/>
      </xsd:choice>
</xsd:complexType>

minOccurs and maxOccurs will constrain the number of occurances inside 
the choice model and they have a default value of 1.

If you have
<xsd:complexType>
     <xsd:choice minOccurs='0' maxOccurs='unbounded'>
          <xsd:element ref='dd'/>
          <xsd:element ref='cc'/>
          <xsd:element ref='aa' minOccurs="2" maxOccurs="2"/>
          <xsd:element ref='bb'/>
      </xsd:choice>
</xsd:complexType>

then you should have pairs of aa elements (one aa element after the other).

Best Regards,
George
