Hi, I noticed a difference in processing of the following example with: Xerces-J 2.6.2 - eats it XSV 2.8 - eats it MSXML 4.0 - reports an error: "The element: 'foo' has an invalid value according to its data type." Schema: <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:simpleType name="fooType"> <xsd:union memberTypes="xsd:string xsd:token"/> </xsd:simpleType> <xsd:element name="foo"> <xsd:simpleType> <xsd:restriction base="fooType"> <xsd:pattern value="[a-z]"/> </xsd:restriction> </xsd:simpleType> </xsd:element> </xsd:schema> Instance: <foo> a </foo> Due to [1]... "For all datatypes ·derived· by ·union· whiteSpace does not apply directly; however, the normalization behavior of ·union· types is controlled by the value of whiteSpace on that one of the ·memberTypes· against which the ·union· is successfully validated." ...I assume that the whitespace of xs:string is used here; thus the value " a " should not be accepted by the pattern "[a-z]". Can someone confirm this? MSXML 4.0 seems to reflect this, the other processors not. The fact that the whitespace-value is at hand when the value was already validated against the member-types, seems to contradict with [2] Datatype Valid, which mandates the pattern facet to be applied first; but without the whitespace-value, normalization is not possible, so applying the pattern facet is not possible as well. Can someone clarify this? [1] http://www.w3.org/TR/xmlschema-2/#rf-whiteSpace [2] http://www.w3.org/TR/xmlschema-2/#defn-validation-rules Regards, Kasimier
