Having not attended the 5 April (apologetically), I believe Peter's
words captures the essence of intent regarding cardinality.

Subject: [soa-rm] Resolution for Issue #520

Issue:
"Line 264, Recommend the beginning of the sentence read, "A specific
instance of a service is provided by one entity..."  This will eliminate
any
confusion concerning multiple organizations (service providers) with
copies
of the implementing service code that could be invoked by different sets
of
service consumers."

Proposed resolution:
-Re-word line 264 to read:
"...A service is provided by an [delete 'one'] entity - the service
provider..."

-Explanation to submitter:
"This was discussed at the committee meeting of 5 April and it was
agreed
that there was room for possible misunderstanding: the reference to 'one
entity' - in the phrase 'A service is provided by one entity' - is not
meant
to imply any cardinality (one, rather than more, entity).
"The Reference Model deliberately avoids cardinality, as it is concerned
with the abstract concept of a service rather than any particular
specific
instance.
"For example, a 'file download service' would be seen by the RM as a
single
service, even if it is implemented as a series of mirror sites that each
provides a tangible 'service'.
"To clarify the text, we propose to change it to..."
