Here is the proposal that that we discussed in today's TC call:
1. Add the following abstract type to sdoModel.xsd:
<xsd:complexType name="DataTypeWrapper" abstract="true"/>
2. Users can use this type to determine when a DataObject is a wrapper:
DataObject someObject = ...
Type dataTypeWrapperType = typeHelper.getType("commonj.sdo",
"DataTypeWrapper");
if (dataTypeWrapperType.isInstance(someObject)) ... // "someObject" is a
wrapper
The actual type of a wrapper object is implementation dependent, but it
will always extend from {commonj.sdo}DataTypeWrapper.
Wrapper types are the special implementation-dependant types used to hold
a simpleType value for an XMLDocument rootObject or for the value of an
anyType property. Formally defined complexTypes that extend simpleType are
not considered wrapper types (i.e., they will not extend DataTypeWrapper),
even though they also have a "value" property.

Re: Fw: [sdo] Issue 118 - Creating wrapper objects for simple types
Hi Blaise,
The two cases that I remember were:
1) reading an anyType property, which maps to sdo:DataObject, but it may
be just a DataType value.
2) the root element of an XMLDocument, which is always returned as a
DataObject, even if the actual document simply had a simple DataType at
the root.

Hi Frank,
For what use case does the user need to know if the type is a data type
wrapper?
