Really, really never wrote a schema line. But wrote some DTDs and know,
that in the DTD model you can write (A|B). Now, I checked the XSD spec,
and _believe_ that the syntax would be stg. like this:
<xs:element name="project">
<xs:complexType>
<xs:choice>
<xs:group ref="masterPOM" />
<xs:group ref="childPOM" />
</xs:choice>
</xs:complexType>
</xs:element>
<xs:group name="masterPOM">
... <!-- current pom model without "extends" tag and with
required elements forced -->
</xs:group>
<xs:group name="childPOM">
... <!-- current pom model with "extends" tag required and with
other master POM elements made optional -->
</xs:group>
