Subject: [bpel4people] New Issue: MaxOccurs Constraint Missing in tFrom
- From: Dieter Koenig1 <dieterkoenig@de.ibm.com>
- To: bpel4people@lists.oasis-open.org
- Date: Tue, 2 Dec 2008 18:17:00 +0100
Target: ws-humantask.xsd
Description: In WS-HumanTask 1.1,
section 3.2.1, the “from” element is defined with zero or more arguments
– the XML Schema definition only has minOccurs=”0” and the missing maxOccurs
attribute implies a default value of 1.
Note that the similar problem does
not occur in bpel4people.xsd as the “argument” is an extension child
element of <bpel:from> which already allows an arbitrary number of
extension child elements.
Proposal: In ws-humantask.xsd,
add maxOccurs=”unbounded” to the “argument” element inside the “tFrom”
definition as shown below.
<xsd:complexType
name="tFrom"
mixed="true">
<xsd:complexContent>
<xsd:extension
base="tExtensibleMixedContentElements">
<xsd:sequence>
<xsd:choice>
<xsd:element
name="argument"
type="tArgument"
minOccurs="0"
maxOccurs="unbounded"
/>
<xsd:element
name="literal"
type="tLiteral"
minOccurs="0"
/>
</xsd:choice>
</xsd:sequence>
<xsd:attribute
name="expressionLanguage"
type="xsd:anyURI"
/>
<xsd:attribute
name="logicalPeopleGroup"
type="xsd:QName"
/>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
