  UPDATE HISTORY:-
  2008.09.22 - d.xml 1.61 - D 1.035/2.019 - Fix for identifiers starting _ and containing numbers.
  2008.08.01 - d.xml 1.60 - D 1.033/2.017 - Merging ddoc.xml 1.14 since there is no advantage to having it separate.
  2008.07.14 - uncommited                 - Added properties: .tupleof, .offsetof
  2008.06.14 - D.XML 1.53 - D 1.030/2.014 - Added user keyword highlighting.
  2008.06.06 - D.XML 1.53 - D 1.030/2.014 - Small fix involving floats starting . in embedded Ddoc.
                                          - Added nothrow and pure attributes (D2.0 only).
  2008.04.09 - D.XML 1.52 - D 1.028/2.012 - Added properties (especially for arrays).
                                          - Added rules for C-Style indenter (thanks vektorboson!)
  2008.02.22 - D.XML 1.51 - D 1.027/2.011 - Changed char rule behaviour on line end.
                                          - Added support for strings ending with c, w or d (must have got lost at some point).
  2008.02.22 - ddoc.xml 1.14              - Fixes/improvements for macros. Highlights first symbol and non-symbols
                                            before as errors; matches embedded brackets () properly.
  2008.01.09 - D.XML 1.50 - D 1.025/2.009 - Changed pragma, version, deprecated matching to use keyword not DetectString.
  2007.12.18 - D.XML 1.49 - D 1.025/2.009 - Fixed some bugs to make the StartingLetter context exit correctly and match identifiers properly.
  2007.12.12 - D.XML 1.48 - D 1.024/2.008 - Adjusted existing contexts somewhat (mostly cleanup).
                                          - Implemented scope context to hightlight exit in scope(exit) etc.
                                          - Adjusted deprecated keyword highlighting.
                                          - Changed layout somewhat.
                                          - Implemented extra highlighting rules for expressions, attributes, etc.
                                          - Changed a lot of colours.
  2007.11.15 - D.XML 1.47 - D 1.023/2.007 - Fixed a few unapperent "bugs" found by checkdtd.
  2007.11.15 - ddoc.xml 1.13              - Fixed a couple of bugs found by checkdtd and changed the version number format.
  2007.11.5  - ddoc.xml 1.12              - Fixed: correct matching of things like /***/ .
  2007.10.11 - ddoc.xml 1.11              - Safety catch: check for unterminated code sections (i.e. check for end of
                                            ddoc comment even in code sections).
                                          - Used DetectIdentifier to (presumably) improve performance.
  2007.10.09 - uncommited - ditto         - Changed some context="#pop" tags to context="#stay" within the normal
                                            context (bugfix for ddoc embedded code highlighting).
  2007.10.9  - ddoc.xml 1.10              - Enabled embedded ddoc code highlighting
  2007.10.9  - ddoc.xml 1.00              - Initial version
  2007.10.08 - D.XML 1.46 - D 1.022/2.005 - Stole Alert and Region Marker highlighting from C++ syntax.
                                          - Added support for DDoc highlighting.
                                          - Reviewed the float regexps again! Tried to make the best of both versions.
  2007.09.17 - D.XML 1.45 - D 1.021/2.004 - Reverted back to old regexps (but fixed hex floats).
                                            Can't combine all float regexps into a single RegExpr element using the '|' operator.
                                            It creates strange problems (like program lock-ups and wrong matches).
                                          - Fix: '=' is allowed in import statements now.
                                          - Fix: character literals are matched correctly now.
                                          - The #line special token sequence is matched fully now (the filespec string needs special handling).
  2007.09.10 - D.XML 1.44 - D 1.021/2.004 - Added __EOF__ to specialtokens.
                                          - Replaced float regexps with more accurate ones. Not sure about speed.
                                          - Fixed Octal regexp not to match 0_ .
  2007.07.24 - D.XML 1.43 - D 1.020/2.003 - Added System to ltypes.
                                          - Improved matching of version declarations.
                                          - Fixed matching of hexadecimal floats.
                                          - Deprecated style is stroked out again.
  2007.07.21 - D.XML 1.42 - D 1.018/2.002 - d.xml validates again according to language.xml.
                                          - HTML entities are highlighted now.
                                          - Numbers before and after the slice operator are not highl. as floats anymore.
                                          - Added C++ to ltypes.
                                          - Improved matching of module/import declarations.
  2007.07.01 - D.XML 1.41 - D 1.017/2.001 - fixed matching of numbers, added deprecated style, minor changes to styles, updated authors line
  2007.07.01 - D.XML 1.40 - D 1.017/2.001 - matches now .di extensions, removed phobos-specific printf/writef and added
                                          - library defined symbols string, wstring, dstring, size_t, ptrdiff_t, hash_t,
                                          - Error, Exception, Object, TypeInfo and ClassInfo
  2007.06.30 - D.XML 1.39 - D 1.017 - matching is much faster now, added "lib" to pragma types, added special tokens,
                                    - /+ +/ can be nested now, numbers are matched more correctly, character literals don't span multiple lines anymore
                                    - escape sequences inside strings and character literals are highlighted,
                                    - non-hex characters in hex strings are highlighted with the Error style,
                                    - using more default styles instead of custom ones
  2007.04.11 - D.XML 1.38 - D 1.011 - ref, macro keywords are now supported, fixed \\ inside a string, updated author
  2007.02.12 - D.XML 1.37 - D 1.006 - bool, foreach_reverse, lazy, scope and typeid keywords are now supported, fixed \"
                                    - inside a string, fixed ending of wysiwyg strings.
  2004.08.15 - D.XML 1.36 - D 0.98  - Current release of D.
                                    - package, writef(strictly speaking writef isn't a keyword) - keywords are now supported.
