Today I had a longer discussion on solving one problem that involved applying some XML schema/type definition technology. We ended discussing two possibilities - XSD and RelaxNG. I was a proponent of XSD just because I believe it is more accepted by a developer community and - of course - because I am much more familiar with it :)

However I am pretty interested if I am right - if the XSD is really more known and accepted by a developer comunity compared to RelaxNG. So I would like to hear your opinion on that subject. The comments section bellow is ready for you...
