Question about nillable=true and minOccurs=0

If you have an element on a complexType that has nillable="true" and minOccurs="0", will the element be de-serialized if the property on the soap stub is set to null?

For instance, let's say a portion of your XSD looks like this:
<xs:complexType name="point" >
    <xs:sequence>
        <xs:element name="x" type="xs:int" nillable="true"  minOccurs="0" maxOccurs="1" />
        <xs:element name="y" type="xs:int" nillable="true"  minOccurs="0" maxOccurs="1" />
    </xs:sequence>
</xs:complexType>

If in your generated soap stub object you set x = null and y = 20, will the de-serialized xml look like this:
<point>
    <x xsi:nil="true" />
    <y>20</y>
</point>

I know that Axis 1.4 (not Axis2) will not de-serialize the element when it is set to null and has minOccurs="0". If need be I can dig up the specific code where this happens.

The question I have is if Axis2 also behaves this way?

Yes it behaves in the same manner.

Thanks,
