Nullable value with xsd.exe generated class

Question

I have been using xsd.exe to generate a class for deserializing XML into. I have decimal value in the source xsd that is not required:

Answer 1

I've just noticed that it has actually included the following code:

private bool balanceFieldSpecified;

[System.Xml.Serialization.XmlIgnoreAttribute()]
public bool BalanceSpecified {
    get {
        return this.balanceFieldSpecified;
    }
    set {
        this.balanceFieldSpecified = value;
    }
}

Which provides the functionality I need.

I'll leave the question open for a while in case there is an elegant way to make use of nullable? type instead.
