Description

<xs:restriction> incorrectly validates the <xs:minInclusive> value against the lexical space as constrained by <xs:pattern> instead of the value space. This issue is very similar to XERCESJ-962.

Schema fragment:

<xs:simpleType name="CurrencyType">
<xs:restriction base="xs:decimal">
<xs:minInclusive value="0"/>
<xs:fractionDigits value="2"/>
<xs:pattern value="(([1-9][0-9]*)|0?)\.[0-9]

{2}"/>
</xs:restriction>
</xs:simpleType>

<xs:simpleType name="AmountType">
<xs:restriction base="CurrencyType"/>
</xs:simpleType>

<xs:element name="grossAmount" type="AmountType"/>

Input element:

<grossAmount>0.11</grossAmount>

Result:

Caused by: [TIAFSchemaValidationException: error = Schema validation error: Error on line 150 of document jcp:com/msdw/taxwith/ecr/validation/revolver.xsd: cvc-pattern-valid: Value '0' is not facet-valid with respect to pattern '(([1-9][0-9]*)|0?)\.[0-9]{2}

' for type 'CurrencyType'.]

Library TIAF uses Xerces to validate an XML document against the schema, revolver.xsd.

To workaround this problem, I've changed 'minInclusive' from '0' to '0.00'.
