But if ever it is done as a html doc, links can be established,
so references to another chapter simply clicked
and the reader surfs the reference, then back to the
page of the link to continue his read.....

I can see many versions of the RDH4 evolving if its in an editable text form,

and complete with modern additions, and then deletions, and then we haven't
got
is RDH4 anymore, maybe NBG10.

If the additions are clearly marked as such, and the edits are done in
such a way that one can see the original with and without edits
(should be easy in html or such) and we could have flame wars over
the validity of the new edits to hammer them to be correct, it
would be great. :-)
