I suspect that the problem is more to do with the limitations of the parser that you're using (you don't say which one?) than your schema, which looks fine by eye. Elements with decimal values must not be empty, unless you've made the element nillable and you have xsi:nil="true" on it in the instance. If you want to restrict the number allowed for ConnectionTimeType then you need to do the restriction of the xs:decimal data type first, to create a new simple type, and then extend that when you define ConnectionTimeType. Something like: <xsd:simpleType name="nonNegativeDecimal"> <xsd:restriction base="xs:decimal"> <xsd:minInclusive value="0" /> </xsd:restriction> </xsd:simpleType> <xsd:complexType name="ConnectionTimeType"> <xsd:simpleContent> <xsd:extension base="nonNegativeDecimal"> <xsd:attribute name="unit" use="required"> ... </xsd:attribute> </xsd:extension> </xsd:simpleContent> </xsd:complexType> [Note: If you have a target namespace and it's not the default namespace, then you'll need to use whatever prefix you're using for it at the start of the reference to the nonNegativeDecimal type.] Cheers, Jeni --- Jeni Tennison http://www.jenitennison.com/
