Attribute must appear/not allowed ?????

[Luís Pereira <lu...@opensoft.pt>]

Hello,

I've tried to submit the following bug but the forms are just too complex
and I couldn't understand (everyone has it's limitations) how to send an
attachment example, so I'm sending it here.

It consists of the following:

1. I've Defined a Schema called Declaration.xsd that you can find in
examples.jar, where I've put a simple type (ValueType, a decimal with 13
of max size and 2 of precision)

<xs:simpleType name="ValueType">
	<xs:restriction base="xs:decimal">
		<xs:minExclusive value="0.00"/>
		<xs:totalDigits value="13"/>
		<xs:fractionDigits value="2"/>
	</xs:restriction>
</xs:simpleType>

2. Then wdefined an Element of that type (Amount), whith a restriction to
have an attribute date that is required and...

<xs:element name="Amount" maxOccurs="unbounded">
	<xs:complexType>
		<xs:simpleContent>
			<xs:extension base="ValueType">
				<xs:attribute name="date" use="required">
					<xs:simpleType>
						<xs:restriction base="xs:date"/>
					</xs:simpleType>
				</xs:attribute>
			</xs:extension>
		</xs:simpleContent>
	</xs:complexType>
</xs:element>

Guess what happens... (you wont, you can run this example using the
following cmd):

  java -cp example.jar;xercesImpl.jar;xmlParserApi.jar Validator

And amazingly for a simple xml file (that you can find inside the jar),
the output will be:

[Error] :4:28: cvc-complex-type.3.2.2: Attribute 'date' is not allowed to
appear in element 'Amount'.
[Error] :4:28: cvc-complex-type.4: Attribute 'date' must appear on element
'Amount'.
[Error] :5:28: cvc-complex-type.3.2.2: Attribute 'date' is not allowed to
appear in element 'Amount'.
[Error] :5:28: cvc-complex-type.4: Attribute 'date' must appear on element
'Amount'.

Can anyone tell me why is this happening ????

Best Regards,
