Whitespace processing in union of token and string based simple types
---------------------------------------------------------------------
Key: XERCESJ-1446
URL: https://issues.apache.org/jira/browse/XERCESJ-1446
Project: Xerces2-J
Issue Type: Bug
Components: XML Schema 1.0 Datatypes
Affects Versions: 2.9.1
Environment: OS: Win XP SP2
SW: Eclipse platform running Oxygen XML plugin with default validation engine
Xerces-J 2.9.1
Reporter: Karthik Sankaran
Priority: Minor
1. "DressSizeType" is a xs:token based simple type with enumerated values
"small" and "large":
<xs:simpleType name="DressSizeType">
<xs:restriction base="xs:token">
<xs:enumeration value="small"/>
<xs:enumeration value="large"/>
</xs:restriction>
</xs:simpleType>
2. "MDressSizeType" is a union type with the above "DressSizeType" as one of
its member types and the other being a string based simple type:
<xs:simpleType name="MDressSizeType">
<xs:union memberTypes="DressSizeType">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="medium"/>
</xs:restriction>
</xs:simpleType>
</xs:union>
</xs:simpleType>
"MDressSizeType" is introduced mainly to add another enumeration value "medium"
to the already existing "small" and "large" enumeration values.
3. An element "dressSize" is assigned the type "MDressSizeType"
4. "dressSize.xsd" is created from 1, 2, and 3. It looks like:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:simpleType name="DressSizeType">
<xs:restriction base="xs:token">
<xs:enumeration value="small"/>
<xs:enumeration value="large"/>
</xs:restriction>
</xs:simpleType>
<xs:simpleType name="MDressSizeType">
<xs:union memberTypes="DressSizeType">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="medium"/>
</xs:restriction>
</xs:simpleType>
</xs:union>
</xs:simpleType>
<xs:element name="dressSize" type="MDressSizeType"></xs:element>
</xs:schema>
5. "dressSize.xml" is created and it looks like:
<?xml version="1.0" encoding="UTF-8"?>
<dressSize xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="dressSize.xsd"> medium </dressSize>
6. When 5 is validated, the value ' medium ' (with leading and trailing
white-spaces) for the "dressSize" element was expected to be invalid as the
enumeration "medium" is encapsulated within a string based simple type whose
whitespace facet value is preserve.
7. But the validation engine accepts the value ' medium ' for
"dressSize" element and informs that the document is valid.
Kindly note: I have made the best possible attempt to scan all the other
reported bugs under this component to avoid a duplicate entry. Apologies in
case I missed out to spot it.
Thanks very much in advance! Appreciate all your efforts...
