[bpel4people] New Issue: MaxOccurs Constraint Missing in tFrom

[Dieter Koenig1 <dieterkoenig@de.ibm.com>]

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>
