Hi Lou and others and many thanks for your participation.
I think that it's a logical choice to think about providing a more general element for such cases. Also I think that we may need to point to an specified portion of an audio or video file with a simple pointing mechanism (in <ptr/> and <ref> elements) [let me know if such a mechanism is present and I couldn't notice that].
Excuse me if I ask my second question again, but I couldn't get an answer yet:
The texts of great importance which may be a subject of teaching which may be treated as a teaching of parts of the main text or some vocal comments or description or so about parts of text. Is it feasible to mark that part of text with <seg> element (if it's not marked with another element) and using corresp or ana attributes? Isn't that an abuse of these attributes? Is there exist any other practice?
Best regards, Saeed
