[bpel4people] New Issue: Location Attribute Mandatory in Result Aggregation

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

Target:

WS-HumanTask CD 05 revision 02, Section 4.7.2 Declarative Result
Aggregation

Description:

Section 4.7.2 defines the <aggregate> element used to combine output from
multiple subtasks.
<htd:aggregate location="query" condition="bool-expr"? function=
"function-call"/>

If a task interface (or an individual WSDL part, see also issue BP-123)
only has one simple-typed element then the location query can be optional.
The aggregation function is then applied to this single simple-typed
element. Example: an approval step which just returns a boolean value.

Proposal:

In section 4.7.2, make the @location attribute optional within the
<aggregate> element:
<htd:aggregate location="query"? condition="bool-expr"? function=
"function-call"/>
(question mark added to @location)

In the explanation, change from:
"The mandatory location attribute MUST contain ..."
to:
"The optional location attribute MUST contain ..."
