If there is this fixed sequence of elements, its similar to XML schema construct for "any one or more of these elements but must be at least one".

Try:

<xs:element name="ContactNumber">
        <xs:complexType>
            <xs:choice>
                <xs:sequence>
                    <xs:element name="home" type="xs:positiveInteger" minOccurs="1" maxOccurs="1" />
                    <xs:element name="work" type="xs:positiveInteger"  minOccurs="0" maxOccurs="1" />
                    <xs:element name="fax" type="xs:positiveInteger"  minOccurs="0" maxOccurs="1" />
                    <xs:element name="mobile" type="xs:positiveInteger"  minOccurs="0" maxOccurs="1" />
                </xs:sequence>
                <xs:sequence>
                    <xs:element name="work" type="xs:positiveInteger"  minOccurs="1" maxOccurs="1" />
                    <xs:element name="fax" type="xs:positiveInteger"  minOccurs="0" maxOccurs="1" />
                    <xs:element name="mobile" type="xs:positiveInteger"  minOccurs="0" maxOccurs="1" />
                </xs:sequence>
                <xs:sequence>
                    <xs:element name="fax" type="xs:positiveInteger"  minOccurs="1" maxOccurs="1" />
                    <xs:element name="mobile" type="xs:positiveInteger"  minOccurs="0" maxOccurs="1" />
                </xs:sequence>
                <xs:sequence>
                    <xs:element name="mobile" type="xs:positiveInteger"  minOccurs="1" maxOccurs="1" />
                </xs:sequence>
            </xs:choice>
        </xs:complexType>
    </xs:element>
