I think one can already use the factory to load different parsers
- based on their features - from the same "implementer" by using
different classnames. (I believe you mentioned AElfred2 as an example)

I would say, reporting the "effective" version for an entity
does not add any information, only removes potentially useful information.
The application already knows the "effective" version from the document
entity's version, so reporting it again and again does not add anything.
However, if an error is encountered it might be useful to know if the
error could be due to an entity's conformance to a different version of XML.
