Intended Usage: This is called if the document is not standalone, that is, it has an external subset or a reference to a parameter entity, but does not have standalone="yes". 
<p>
If this handler returns EStatusError, then processing will not continue, and the parser will return a ENotStandalone error. If parameter entity parsing is enabled, then in addition to the conditions above this handler will only be called if the referenced entity was actually read. <dl compact><dt><b>Exceptions:</b></dt><dd>

Intended Usage: This is called in two situations: 1) An entity reference is encountered for which no declaration has been read *and* this is not an error. 
<p>
2) An internal entity reference is read, but not expanded, because the default has been called. Note: skipped parameter entities in declarations and skipped general entities in attribute values cannot be reported, because the event would be out of sync with the reporting of the declarations or attribute values. <dl compact><dt><b>Exceptions:</b></dt><dd>
