It certainly looks very powerful. No doubt about that.

So what does that resolve to, an xpath? or something like that and
what languages are there currently implementations for?

Would it be used like this ? :

 (a) docno := myDoc.ReadIntegerElement('d.t.2_8');

to replace:

 (b) docno := myDoc.ReadIntegerElement('/references/document_number');

If so, I think it is a pretty useful piece of element mapping technology

Hardcoding xpaths, while on the surface looks good, immediately falls
apart with different document formats, and particularly with different 

 docno := myDoc.ReadIntegerElement(LocalisedXPath('d.t.2_8','EN'));
 docno := myDoc.ReadIntegerElement(LocalisedXPath('d.t.2_8','DE'));

and of course back the other way (writing):


would set the document, modifying everything for the German locale...
