> TUSCANY-521 exposed a consistent set of integer indices to API visible Properties,  and a mapping to the internal EMF indices which had previously been exposed. Some effort was made to preserve the capacity to generate classes that exhibit multiple inheritance,  but 1) it was not clear that multiple inheritance was unbroken,  and 2) there was no way to describe multiple inheritance as input to the generator.  The work that went into the TUSCANY-521 effort to permit generation of SDO classes that exhibit multiple inheritance will be attached here. 
> Completion of this JIRA will require modification of the SDOClass.javajet file to ensure that the internal and external indices are used appropriately when the code path through the generator exercises the multiple inheritance features.  Note that this code path also currently exhibits elements of the old generator pattern where EMF code appeared directly in the generated classes. 
> Note also that the multiple inheritance case may cause discontinuous use of index constant values within a given class,  hence the reason why the generated internalConverIndex() method  is implemented with a switch statement rather than arithmetic.
