<xs:schema targetNamespace="http://www.w3.org/2002/ws/databinding/examples/6/09/" elementFormDefault="qualified">
<xs:simpleType name="UnionSimpleDateString">
<xs:union>
<xs:simpleType>
<xs:restriction base="xs:date"/>
</xs:simpleType>
<xs:simpleType>
<xs:restriction base="xs:string"/>
</xs:simpleType>
</xs:union>
</xs:simpleType>
<xs:element name="unionSimpleDateString" type="ex:UnionSimpleDateString"/>
<xs:element name="echoUnionSimpleDateString">

</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

The example schema [UnionSimpleDateString.xsd] has been classified as being an Advanced XML Schema Patterns for Databinding 1.0 conformant document as it only exhibits the following patterns:

Status Nodes Name XPath
basic TargetNamespace .[@targetNamespace]/ (., @targetNamespace)
basic QualifiedLocalElements .[@elementFormDefault = 'qualified']/ (@elementFormDefault)
basic UnqualifiedLocalAttributes .[not(@attributeFormDefault) or @attributeFormDefault = 'unqualified']/ (., @attributeFormDefault)
basic IdentifierName .//.[matches(@name, "^[A-Za-z_]([A-Za-z0-9_]0 31)$")]/ (@name)
basic GlobalElement ./xs:element[@name and @type and contains(@type, ':')]/ (., @name, @type)
basic GlobalSimpleType ./xs:simpleType[@name]/ (., @name)
basic ComplexTypeSequence .//xs:complexType/xs:sequence/ (., xs:element/(., @name))
basic GlobalElementSequence ./xs:element[@name]/xs:complexType/xs:sequence[xs:element]/ (../../(., @name), .., ., xs:element/(., @name))
basic SequenceElement .//xs:sequence/xs:element/(.)
basic ElementTypeReference .//xs:element[@name and @type and namespace-uri-from-QName(resolve-QName(@type,.)) != 'http://www.w3.org/2001/XMLSchema' and contains(@type, ':')]/ (., @name, @type)
basic ElementReference .//xs:element[@ref and contains(@ref, ':')]/ (., @ref)
advanced UnionSimpleTypes .//xs:simpleType/xs:union[not(@memberTypes)]/xs:simpleType/ (.., .)
advanced SimpleTypeRenamed .//xs:simpleType/xs:restriction[@base and count(./*) = 0]/ (., @base)

To facilitate testing, the example schema element has been wrapped in the following descriptions:

The following valid instance documents are provided:

Instance Validity
UnionSimpleDateString01 true
UnionSimpleDateString02 true

  <ex:unionSimpleDateString>Monday Night</ex:unionSimpleDateString>
  <ex:unionSimpleDateString>2006-06-06</ex:unionSimpleDateString>
