> Currently (unexpanded) entity references are represented as OMText instances with type=ENTITY_REFERENCE_NODE. This is a bad choice:
> * An entity reference doesn't necessarily represent character data: the expansion can e.g. produce elements. Representing it as an OMText is therefore conceptually wrong.
> * There is lots of code that checks for OMText and then uses OMText#getText() under the assumption that the return value represents character data. However, for an entity reference, getText() would return the entity name.
> It should also be noted that the test coverage for entity references is currently almost nonexistent. As a result, the code that handles entity references is inconsistent. E.g. OMStAXWrapper/SwitchingWrapper contains the following code:
>             if ((currentEvent == START_ELEMENT)
>                     || (currentEvent == END_ELEMENT)
>                     || (currentEvent == ENTITY_REFERENCE)) {
>                 return ((OMElement) lastNode).getLocalName();
>             } else {
>                 throw new IllegalStateException();
>             }
> This is obviously incorrect.
