[xsd-users] When present function is created?

[wendy f]

Hello all,
CaseI:


<xs:element name="person">

   
  <xs:complexType>

       
    <xs:sequence>
     
      <xs:element name="child_name" type="xs:string" minOccurs="0"/>

       
    </xs:sequence>

   
  </xs:complexType>

</xs:element>

CaseII:


<xs:element name="person">

   
  <xs:complexType>

       
    <xs:sequence>
     
      <xs:element name="child_name" type="xs:string"/>

       
    </xs:sequence>

   
  </xs:complexType>

</xs:element>

In caseI, the generated C++ code will support the function 'present'. However, in caseII, the generated C++ code will NOT support the function 'present'.
By default, the value of minOccurs is 1.

Question> Is there a way that we can force the XSD always supports 'present' function?

Thank you
