XMLElementAttribute and IsNullable=True

[Ganesh Muthuvelu]

Hello,
When setting the XMLElementAttribute IsNullable=false I get the minOccurs=0
in my WSDL:

VB .NET:
<XmlElementAttribute(IsNullable:=False)> Public Quantity As String = ""
WSDL:
<s:element minOccurs="0" maxOccurs="1" name="Quantity" type="s:string" />

When setting the XMLElementAttribute IsNullable=True, I get the minOccurs=1
in my WSDL:

VB .NET:
<XmlElementAttribute(IsNullable:=True)> Public Quantity As String = ""
WSDL:
<s:element minOccurs="1" maxOccurs="1" name="Quantity" type="s:string" />

How can I set IsNullable=true and keep minOccurs="0"?

Any ideas?

Thanks,
Ganesh
