Here's the file i made basing on DTDs for projectxml.
Created attachment 123073 [details] projectxml.vim
Created attachment 123086 [details] projectxml.vim Some improvements over the initial work: 1. New header with the correct authors. Maintain the license and give proper credit to ciaranm. 2. Removed the redudants projectxmlElements (as it inherits from guidexml). Also alpha order the list to manage it easier. 3. The same with projectxmlAttr. Added some missed attributes. Rane, please give it a try. If all is ok, I will generate the patch, including the ftdetect file and this one. Thanks.
It's already implemented in the newest gentoo-syntax. :-(
