Do you mean that you want the key for the first person to be
<'bob','blue'> and the key for the second person <'sally','blue'>?

This would be possible if the following key definition were allowed

<xs:key name="test">
 <xs:selector xpath="person"/>
 <xs:field xpath="@name"/>
 <xs:field xpath="car[1]/@color"/>
</xs:key>

But as things stand that's not allowd.

Feel free to send a suggestion for a 1.1 or 2.0 requirement to
