It's interesting, but I don't think it is suitable for a core feature.
Could you split the patch into a core-patch and an extension module?
The extension module would be put in contrib or in a pgFoundry project.
XML might be good for communications between the core and the module;
XML-explain was ongoingly discussed, but had not been completed yet.
