PROBLEM

See section 2.1.3 (second part) of 
http://www.oasis-open.org/committees/download.php/26722/SDO_XML_Issues.doc

PROPOSED RESOLUTION

Resolution as described in section 2.1.3. More specifically:

In section 9.3.2. change:

A single property is used for all the elements with the same local name 
and the same targetNamespace, where isMany=true. 

to the following:

A single property is used for all the elements with the same local name 
and the same targetNamespace. If the content model allows more than 1 
instance of the element, then isMany=true. If, however, the elements are 
mutually exclusive (for example, they are single valued and on two sides 
of a xsd:choice group), then isMany=false.
