From
https://lists.oasis-open.org/archives/emix-comment/201208/msg00000.html

the draft minutes at
https://www.oasis-open.org/committees/document.php?document_id=47493&wg_abbrev=emix
.

Thank you for your comment. This is a partial response to item 4.
The XML Schema specification has default minOccurs and maxOccurs
equal to 1. The XML schema is normative; the UML model is generated
by a tool (Sparx Enterprise Architect) from the schemas. The
multiplicity is explicit in the underlying UML model.  Enterprise
Architect does not always show the multiplicity when it is the
default 1..1.
The UML models in the OASIS document archive all show 1..1 where
that is desired; Enterprise Architect 9 does not generally display
multiplicities that are 1..1.
Please reference the normative XML artifacts for clarification of
multiplicity/cardinality; OASIS defines the machine-readable XML
artifacts as controlling where there is any conflict between the
specification and the normative XML artifacts.
We have noted that a future revision of the specification should
consider stating multiplicity in the introductory material.
END DRAFT
Thanks!
bill
