+// g++ -Wall -O2 contrib/html5-printer.cpp -o html5-printer -ltinyxml2
+
+// This program demonstrates how to use "tinyxml2" to generate conformant HTML5
+// by deriving from the "tinyxml2::XMLPrinter" class.
+
+// http://dev.w3.org/html5/markup/syntax.html
+
+// In HTML5, there are 16 so-called "void" elements. "void elements" NEVER have
+// inner content (but they MAY have attributes), and are assumed to be self-closing.
+// An example of a self-closig HTML5 element is "
" (line break)
+// All other elements are called "non-void" and MUST never self-close.
+// Examples: "".
+
+// tinyxml2::XMLPrinter will emit _ALL_ XML elements with no inner content as
+// self-closing. This behavior produces space-effeceint XML, but incorrect HTML5.
+
+// Author: Dennis Jenkins, dennis (dot) jenkins (dot) 75 (at) gmail (dot) com.
+// License: Same as tinyxml2 (zlib, see below)
+// This example is a small contribution to the world! Enjoy it!
