A question about derived lists. Suppose I have a simpleType named
"US-State" (lifted from the Primer) that looks like this:

<xsd:simpleType name="US-State" base="xsd:string">
    <xsd:enumeration value="AK"/>
    <xsd:enumeration value="AL"/>
    <xsd:enumeration value="AR"/>
    <!-- and so on -->
</xsd:simpleType>

And then wanted to create an element to contain a list of exactly six
states (also from the Primer):

<xsd:simpleType name="SixUS-States" base="US-State"
derivedBy="xsd:list">
    <xsd:length value="6"/>
</xsd:simpleType>

Is there anything that keeps the content of the SixUS-States element
from being, say "AK AK AK AK AK AK"? That is, when you derive a list
from a set of values, can a value be used more than once in the list and
the element still be valid?

Thanks,
Liz
