No, this will use the type "Book".

> or do we say
> <book xsi:type="Book1">
>     <title>XYZ</title>
>    <author>ABC</author>
>    <author>DEF</author>
> </book>

Yes, this will use the type "Book1" so if you do:

<book xsi:type="Book1">

you will receive a validation error.

> I think it should be the latter?
