Re: [sdo] NEW ISSUE: COR07110006 and COR07110007 need to be refactored.

[Bryan Aupperle <aupperle@us.ibm.com>]

Proposed refactorings

The type of the created property will not
necessarily be identical to the type of the value read from an element,
since, in the case of multi-valued properties it is possible that the types
of the elements do not agree. If an element contains an xsi:type attribute,
the value MUST be used to determine the type of the value. [COR07110006]
If no xsi:type attribute is present and the content is simple, then the
value's type will be implementation dependent. An SDO Implementation MAY
use wrapper objects (see 7.10: Corner
Cases, point 4) to contain simple values.
[COR07110009] If the content is complex, the value MUST be interpreted
as an instance of OpenSequncedType; an implementation MUST provide a single
Type to handle all the elements. [COR07110010] 

An implementation MUST define the property
type such that all the values of the property conform, and the type information
is available. [COR07110007] If the property is single valued, or if the
type of all elements in a multi-valued property agree, an SDO implementation
MUST either create the property of the value type itself or create the
property with a more general type, such as {http://docs.oasis-open.org/ns/opencsa/sdo/200911}Object
or {http://docs.oasis-open.org/ns/opencsa/sdo/200911}DataObject.
[COR07110011] Applications are expected to use meta-data introspection
to determine the contents and structure of the received data objects.

Target: Core Spec CD03-WD3

Description: Normative statements COR07110006 and COR07110007 each contain
several statements expressing a mixture of MUSTs and MAYs.  Normative
statements should be single statements and should not mix MUSTs and MAYs.

Proposal: Split each of COR07110006 and COR07110007 into multiple statements.
