I never understood the terrible bloat of XML - why, oh why, when equally 
powerful yet eminently more readable and vastly more efficient options are 
available - options that are even easier to parse than XML too.
http://www.yaml.org
http://www.json.org

With the rapid spread of AJAX technology and AJAX really increasingly becoming 
AJAJ (using JSON for object serialization instead of XML), JSON looks like a 
safe bet.

I think when "managers" dream up health messaging, they have to come with a 
convoluted ambiguous monstrosity like HL7 - and when they dream up a 
universal data exchange format, they come up with XML. Certainly not the 
doings of real life software engineers ...
