" Vim syntax file
" Language:	XML
" Maintainer:	Johannes Zellner <johannes@zellner.org>
"		Author and previous maintainer:
"		Paul Siegmann <pauls@euronet.nl>
" Last Change:	2013 Jun 07
" 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
