+" Vim syntax file
+" Language: XML
+" Maintainer: Johannes Zellner <johannes@zellner.org>
+" Author and previous maintainer:
+" Paul Siegmann <pauls@euronet.nl>
+" Last Change: Mi, 13 Apr 2005 22:40:09 CEST
+" Filenames: *.xml
+" $Id: xml.vim,v 1.3 2006/04/11 21:32:00 vimboss Exp $
+
+" CONFIGURATION:
+" syntax folding can be turned on by
+"
+" let g:xml_syntax_folding = 1
+"
+" before the syntax file gets loaded (e.g. in ~/.vimrc).
+" This might slow down syntax highlighting significantly,
+" especially for large files.
+"
+" CREDITS:
+" The original version was derived by Paul Siegmann from
+" Claudio Fleiner's html.vim.
+"
+" REFERENCES:
+" [1] http://www.w3.org/TR/2000/REC-xml-20001006
+" [2] http://www.w3.org/XML/1998/06/xmlspec-report-19980910.htm
+"
+" as <hirauchi@kiwi.ne.jp> pointed out according to reference [1]
+"
+" 2.3 Common Syntactic Constructs
+" [4] NameChar ::= Letter | Digit | '.' | '-' | '_' | ':' | CombiningChar | Extender
+" [5] Name ::= (Letter | '_' | ':') (NameChar)*
+"
+" NOTE:
+" 1) empty tag delimiters "/>" inside attribute values (strings)
+" confuse syntax highlighting.
+" 2) for large files, folding can be pretty slow, especially when
+" loading a file the first time and viewoptions contains 'folds'
+" so that folds of previous sessions are applied.
+" Don't use 'foldmethod=syntax' in this case.
+
+
+" Quit when a syntax file was already loaded
