Re: [xsl] Overlapping structures

[Patrick Durusau <pdurusau at emory dot edu>]

Suart,

I only have time for a brief note (major analysis due out later today)
but you might want to take a look at:

http://www.sbl-site2.org/Extreme2001

There you will find the presentation (and paper, other resources) that
Matthew O'Donnell and I did at the Extreme Markup Languages Conference
(Montreal 2001) on implementing concur in XML. Uses XSLT for building
the concurrent markup file, allows authoring of concurrent structures in
simple text/XML editors, etc.

This is very much an in progress effort, we are starting to work on
visualization of overlapping structures. The paper (also at the site)
notes several other areas of ongoing research and development.

Hope this helps!

Patrick
