Robert,

I guess, as far as this IG is concerned, we can/should restrict ourselves to eBooks, more precisely ePub. In the case of an ePub, the EPUB CFI specification:

http://www.idpf.org/epub/linking/cfi/epub-cfi.html

becomes part of the picture... I am not sure it answers to your requirements, though, because I am not sure whether the existing fragment id-s (in HTML or in SVG) can be combined easily...

I guess Brady can help us out for this.

Ivan
