XSD tool appends “Specified” to certain properties/fields when generating C# code

Question

I got a strange behaviour with the XSD generator I can\'t really explain. I got an XSD like this:

Answer 1

Set minOccurs="1" where element is nillable. For example:

<xs:element name="StageOnDemand" type="xs:boolean" nillable="true" minOccurs="1" />

Answer 2

the bool attribute means the related attribute should be serialized.

e.g.

If the bool MinDuration_100msSpecified is set to false, and you set the MinDuration_100ms to be 300, when you use XmlSerializer to serialize the object, the MinDuration_100ms attribute won't be serialized.

This feature can save the serialized xml file to be minimal.
