Thanks, Mike for the answers.

There's a slight correction to the schema I wrote. The correct schema
fragment is below:

<xs:element name="price" maxOccurs="unbounded">
   <xs:complexType>
	<xs:simpleContent>
	    <xs:extension base="xs:double">
	      <xs:attribute name="effective" type="xs:date" />
	    </xs:extension>
	</xs:simpleContent>
    </xs:complexType>
</xs:element>

Just thought of writing this here, to make the archives useful.
