Many thanks Troy, that is a very helpful posting.

I will experiment with this and come back to you.

I fully agree and this is what I am trying to achieve. My difficulty is in creating the proper OSIS references. But, I think i am getting there.

Is this why we have weird behaviour in Xiphos (and possibly other places too, butI have not checked) when references do not contain an OSIS ref?

<note type="crossReference"><reference>Apg 7,14</reference><note>

This should to my mind not get parsed but simply be presented as a plain "not "clickable" text "Apg 7,14". 

It should be up to the module maker to create proper crossreferences in correct OSIS marking up and should not be the engine's job at the rendering time to present a nice "clickable" out of poor input. Otherwise we will get all kinds of mess - as we do already in a variety of modules.

But - and I think this is where the engine comes in - any enhancements on the parsing engine during module builds are hugely useful. As they are to decipher user input.
