XML-schema: Equivalent to nullable="true" for attributes?

Question

Hi,

I have been having problem with adding type="date" in my schema, as whenever it is null it throws a marshalling error. I found out that for elements we can add an attribute like nullable="true" and get rid of this issue. But, wasn't able to find similar way for attributes. Is there a way to avoid this issue for attributes?

Thanks!

There is no "nillable" option for attributes, unfortunately.

You can however adorn an attribute with a use="optional" specifier which should take care of the case where the attribute is not present (shouldn't cause an error).
