Look at element and attribute wildcards (<any/> and <anyAttribute/>
respectively). They subsume the functionality of the old model=open/closed
attribute. Both of these are described in Part 1 of the Dec 17 PWD (section
3.5).

Had your "Book" type been defined as follows:

>       <element name="Book">
>            <type>
>                <element name="Title" type="string"/>
>                <element name="Author" type="string"/>
>                <element name="Date" type="string"/>
>                <element name="ISBN" type="string"/>
>                <element name="Publisher" type="string"/>
>                <any minOccurs='0' maxOccurs='*'/>
>            </type>
>       </element>


You would have been fine.
