Since we have now a few new tags in our GuideXML syntax, i think we should have them included in the syntax files for vim. Adding those two lines in /usr/share/vim/vimfiles/syntax/guidexml.vim should do the trick: syn keyword guidexmlElement contained dd dt dl syn keyword guidexmlElement contained ident stmt keyword const var Thanks in advance for fixing this little issue. Details on new tags are here: http://www.gentoo.org/doc/en/xml-guide.xml#doc_chap2_sect7
This bug is so old that it went outdated. Neysx's patch in #145999 will do all the job now. *** This bug has been marked as a duplicate of 145999 ***
