In the Web Service XML Maps (both Inbound and Outbound) you can set both the Nillable and MinOccurrs attributes for a field. You can find more info on this by pulling up the Help -> Contents and Index in the Admin tool and viewing the entry on XML editing.

I have no idea why they skipped that important attribute. In XML there is a "nillable" attribute/concept that will allow the element to not be there. It is my understanding that nillable allows the XML element to have no contents. Ref: http://www.w3.org/TR/xmlschema-1/#xsi_type " xsi:nil XML Schema: Structures introduces a mechanism for signaling that an element should be accepted as *valid* when it has no content despite a content type which does not require or even necessarily allow empty content. An element may be *valid* without content if it has the attribute xsi:nil with the value true. An element so labeled must be empty, but can carry attributes if permitted by the corresponding complex type. " While the XML minOccurs attribute/concept allows the element to not be in the xml at all.( "<element/>" vs "") However, I think the rub in this case is that in the Java universe (and apparently in the .Net universe too) there are some data types that can not be "null". So I think the real issue is likely the XML dataType for the element instead of these other issues. :) Maybe if you use a dataType that is a full object instead of a primitive that would allow Java/.Net to deal with an "optional primitive" data element. Maybe "integer" would map to the object classes in Java/.Net? Just a thought.
