XML schema: how to have multiple identical elements?

Question

It is very difficult for me to build my first XML schema. I need to check the validity of the XML document that forms the questionnaire.
So, here the section fails:

I changed the source. The first answer relates to this code:

<root>
    <values>
        <value>Lorem</value>
        <value>ipsum</value>
        <value>dolor</value>
    </values>
</root>

Now my actual goal is this:

<requires>
    <require requires-id="2" type="included">
        <values>  
            <value isRequired="true">Lorem</value>
            <value isRequired="false">Lorem</value>
            <value isRequired="false">Lorem</value>
        </values>
    </require>
    <require requires-id="5" type="excluded">
        <values>  
            <value isRequired="true">Lorem</value>
            <value isRequired="false">Lorem</value>
        </values>
    </require>
</requires>

Can anyone help to make the correct diagram? I am using the Sun Multi-Schema XML Validator (MSV) to validate a schema document.

Thanks in advance,
Steph

Answer 1

This should do it for the first xml:

<xs:complexType name="Values">
    <xs:sequence>
        <xs:element name="value" minOccurs="0" maxOccurs="200">
            <xs:complexType>
                <xs:simpleContent>
                    <xs:extension base="xs:string">
                        <xs:attribute name="isOnlyOption" type="xs:boolean"/>
                    </xs:extension>
                </xs:simpleContent>
            </xs:complexType>
        </xs:element>
    </xs:sequence>
</xs:complexType>
<xs:element name="values" type="Values" minOccurs="0"/>

The second is as follows:

<xs:element name="requires" minOccurs="0">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="require" minOccurs="1" maxOccurs="200">
                <xs:complexType>
                    <xs:attribute name="requires-id" type="xs:IDREF"/>
                    <xs:attribute name="type" type="RequiresType"/>
                    <xs:all>
                        <xs:element name="values" type="Values" minOccurs="0" maxOccurs="1"/>
                    </xs:all>
                </xs:complexType>
            </xs:element>
        </xs:sequence>
    </xs:complexType>
</xs:element>
