Another thing u can try is the following:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="father" type="xs:string"/>
<xs:element name="mother" type="xs:string"/>
<xs:element name="son" type="xs:string"/>
<xs:element name="daughter" type="xs:string"/>
<xs:element name="pet" type="xs:string"/>
<xs:element name="family">
<xs:complexType>
<xs:sequence>
<xs:choice minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="father"/>
<xs:element ref="mother"/>
<xs:element ref="son"/>
<xs:element ref="daughter"/>
<xs:element ref="pet"/>
</xs:choice>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
That will allow multiple sets of parents but allows any order.
