Hope that helps It might be a bit unintuitive (and caught me off guard and reeling, too!) - but it's the only proper way to handle elements that might or might not be specified in your XML schema. And it also might seem counter-intuitive that you have to set the xyzSpecified flag yourself - but ultimately, this gives you more control, and WCF is all about the Four Tenets of SOA of being very explicit and clear about your intentions.

Attribute for XSD to prevent XSD.exe FieldSpecified flags
Hope this helps There is no flag to change the behaviour - it is all driven by the XSD. Enums are non nullable. Your attribute is optional (the default value of the use attribute in XSD), and so the xxxSpecified properties are needed to control the serialization of the associated fields (in your case the addrLineTypCdField field).
I wish this help you A decimal point is punctuation that marks where the integer digits of a number end and the fraction digits begin. For example, in the sentence “Pi is about 3.14”, the period is a decimal point. The 3 represents a number of ones, and the 1 represents a number of tenths. A binary point is the same as a decimal point but is used when referring to binary numerals, such as “11.00100”. A radix point is the same thing for any radix (any base used for a positional numerical system).
