Think of it the other way around: if the value can't be nill then what point is there in having a default? If it is nill, then you're telling people what value is used instead... On Wed, Jul 10, 2019 at 7:01 AM Costello, Roger L. < costello@m...> wrote: Hi Folks,
The following XML Schema declares an element to be nillable and the element has a default value:
<xs:element name="test" type="xs:string" nillable="true" default="Hello, world" />
That is legal but is it meaningful?
What does this (schema-valid) XML instance mean:
<test xsi:nil="true"></test>
xsi:nil="true" indicates that there is no information available for the <test> element. The default value indicates that there is information available for the <test> element and the information is "Hello, world".
Right?
Isn't that a contradiction?
