I think you would need to define the range rather than the "length". Afaik the length attribute is for string types only.

In this case you would probably need the following:

<xs:minInclusive value="0"/>
<xs:maxInclusive value="999"/>

Ok so I create a simpleType - call it "myInteger"
but when i link company element to the new type I get a type not declared error in validation
I'm adding the type in the line after schema url - is this correct?


<xs:element name="company" type="xs:myInteger"/>

<xs:simpleType name="myInteger">
 <xs:restriction base="xs:integer">
  <xs:minInclusive value="0"/>
  <xs:maxExclusive value="999"/>
 </xs:restriction>
</xs:simpleType>

mark renton

<xs:element name="company" type="xs:myInteger"/>

schoolboy errer xs needs to be removed

<xs:element name="company" type="myInteger"/>
