Mark, try this:

  <element name='exporteditems'>
            <simpleType>
             <list itemType="ID">
                        <length value="6"/>
             </list>
            </simpleType>
 </element>

All the best, Ashok

Subject:  RE: Element containing a list of IDs



Thanks Henry. I had looked at tge US States example, the spec, and all the
posts containing "<list" and couldn't see what is wrong with my stuff. I
want to do this with anonymous types (hence my following one of the posts
rather than the US States example as my template). I realise my stuff is
wrong, but not why, and therefore not how to fix it. I guess the problem is
in my failure to properly anonymise the example?

I've just tried again starting from the example as you suggested but am
hitting the same problem. I guess I'm doing something really stupid!

Aiming slighly lower I ended up with...
    <element name='exporteditems' minOccurs='0' maxOccurs='1'>
            <simpleType>
             <list itemType="ID"/>
           <restriction>
              <length value="6"/>
             </restriction>
            </simpleType>
    </element>

I don't want the length restriction but before getting to the point of
removing it I'm getting the same complaint from XSV...

> Invalid cvc-complex-type.1.2.4: element
{http://www.w3.org/2000/10/XMLSchema}:restriction > not allowed here in
element {http://www.w3.org/2000/10/XMLSchema}:simpleType

I'm a novice at this stuff so would appreciate even the most obvious of my
errors and misconceptions being brutally highlighted.

Thanks

Mark

So look at the DTD or Schema or the spec. itself [1], or best of all
the Primer [2], where you will find


List Type for Six US States:

            <xsd:simpleType name="USStateList">
             <xsd:list itemType="USState"/>
            </xsd:simpleType>

            <xsd:simpleType name="SixUSStates">
             <xsd:restriction base="USStateList">
              <xsd:length value="6"/>
             </xsd:restriction>
            </xsd:simpleType>

The USStateList type is directly relevant to your needs, just copy,
change the itemType and anonymise.  The SixUSStates example shows the
way forward for a more complex case.
