Overlapping trees in XML

less than 1 minute read

xmlhack: One tree isn’t enough talks about a couple of proposals for encoding overlapping trees.

LMNL is a non XML markup language which allows for overlapping ranges.JITT (Just in time trees) is an XML based system which can derive different trees by parsing the file differntly. They have a page on Overlapping Hierarchies/Concurrent Markup.

This looks like it deserves some more attention.
