The lines 1351-1352 define business process as "a description of the tasks, participants' roles and information needed to fulfill a business objective"

I think, this definition requires re-consideration and clarification because it is in the conflict with the business process definitions used in Business and Technology while not representing any special service-oriented value (which could be referred to justify the differences). In particular,

1) definition of the term 'business process' in Business has two meanings: a) 'business process'='business capability'; 2) 'business process'='ordered sequence of business actions taken in accordance with the process business logic'. In IT, the latter definition is predominant. None of the definitions
are just 'descriptions'.

2) A description of the business process (BP) in Business includes process tasks and business objectives but not necessary all participants' roles e.g., where the BP is a business capability. In the 'case of capability', the roles of process' activity providers (the participants) are immaterial because such definition of the process cares about the activity results only, not about the activity providers. BTW, this is the very definition that allows the full
replacement of the notion of business process by the notion of service orchestration in a composite/aggregate service.

3) A description of the BP includes not only "information needed to fulfill a
business objective" (i.e. input information) but also information describing the process'
RWE and, desirably, information about the process Execution Context (Business and
Technical).
