Proposed text for identification attribute on <perform />, as original choreology proposal 5
The name "subChoreographyInstanceId" should be aligned with the attribute used in finalize.
In 2.5.3, Composing Choreographies
Change first line of perform syntax from 
    <perform choreographyName="qname">
    <perform choreographyName="qname" subChoreographyInstanceId="XPath-expression">

The subChoreographyInstanceId attribute defines an identifier for this performance
of the Choreography identified by the choreographyName attribute. If that Choreography
can only be performed once within this enclosing choreography, the subChoreographyInstanceId
attribute is optional. Otherwise, it is required and the value MUST be different for
each instance in which <perform /> is run (?) for the identified inner Choreography.
(This is a dynamic requirement - e.g. if a single <perform /> element appears
in a workunit that can repeat, each use of perform must assign a different
subChoreographyInstanceId value.)
