anyType question 2003-02-05 - By Jesus M. Salvo Jr.
Given the following snippets from a schema definition ( look in
particular on the element name "Details" .. ):
<xs:complexType name="responseStatusType">
<xs:annotation>
<xs:documentation>Status information conveyed in
responses</xs:documentation>
</xs:annotation>
<xs:all>
<xs:element name="StatusCode">
<xs:simpleType>
<xs:restriction base="tns:statusCodeType"/>
</xs:simpleType>
</xs:element>
<xs:element name="StatusText" type="tns:statusTextType"/>
<xs:element name="Details" type="tns:anyDataType"
minOccurs="0"/>
</xs:all>
</xs:complexType>
... and this ...:
<xs:complexType name="anyDataType">
<xs:annotation>
<xs:documentation>Any element and attribute </xs:documentation>
</xs:annotation>
<xs:complexContent>
<xs:restriction base="xs:anyType">
<xs:sequence>
<xs:any processContents="lax" minOccurs="0"
maxOccurs="unbounded"/>
</xs:sequence>
</xs:restriction>
</xs:complexContent>
</xs:complexType>
... and given the following snipped from the XML document:
<Status>
<StatusCode>4001</StatusCode>
<StatusText>Improper identification</StatusText>
<Details>Not a valid VASPID</Details>
</Status>
JAXP + Xerces 2.2.1 with schema validation reports this error:
org.xml.sax.SAXParseException: cvc-complex-type.2.3: Element 'Details'
must have no character [children], because the types content type is
element-only.

It's complaining about the Details element ... but I thought
that <xs:restriction base="xs:anyType"> means that you can have a string
in there, based on this tree:
http://www.w3.org/TR/xmlschema-2/#built-in-datatypes
... where string a is an anySimpleType which in turn is an anyType,
which is the base restriction of the completxType anyDataType?
Am I wrong?
