Hi,
You almost had it. You need an extra xs:simpleType element in there.
Also, you don't want to use itemType - it's an either/or thing - either
you specify the itemType attribute OR a simpleType child.
<xs:element name="ABNFRULES ET" type="xs:token" maxOccurs="1">
<xs:simpleTyp e>
<xs:list>
<xs:simpleTyp e>
<xs:restricti on base="xs:token" >
<xs:pattern value="\p{IsBas icLatin}*"/>
</xs:restriction>
</xs:simpleType>
</xs:list>
</xs:simpleType>
</xs:element>
Some more examples of list types are at:

Hope that helps,

=============== =============== =============== =============== ===
And now when I give it to the validator I get the following
=============== =============== =============== =============== =
For attribute '???', either the name or the ref attribute must be
present, but not both.
If ref is present, all of 'simpleType', 'form', 'type', and 'use' must
be absent.
The referring attribute must be present.
=============== =============== =============== =============== =
This is the web based validator at the w3school site and it doesnt show
the line numbers so I cant figure out where exactly is the problem.
Ant help will be appreciated
Also can someone point me to a good freeware which can validate xsd
thanks
