Your analysis is essentially correct, but this is not a change from
the first edition.
The best you can do is make the implicit choice explicit, and use
local declarations:
<xsd:complexType name="Purchase-Derivant">
<xsd:complexContent>
<xsd:restriction base="r:PurchaseOrderType" >
<xsd:sequence>
<xsd:element name="shipTo" type="xsd:string"/>
<xsd:choice>
<xsd:element name="amount" type="xsd:positiveInteger"/>
<xsd:element name="price" type="xsd:positiveInteger"/>
</xsd:choice>
</xsd:sequence>
</xsd:restriction>
</xsd:complexContent>
</xsd:complexType>
