XPS (and OpenXPS) is not dependent on WPF. Many third parties have implemented XPS support on a variety of platforms, including Mac OS X, Linux and various embedded platforms. Likewise, TC46, the technical committee behind OpenXPS, expects multiple independent implementations of the format.</p> <p>Hope that explains /aiddy </p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=9843686" width="1" height="1">http://blogs.msdn.com/b/xps/archive/2009/07/16/hello-ecma-388-1st-edition.aspx#9840069Sun, 19 Jul 2009 17:55:07 GMT91d46819-8472-40ad-a661-2c78acb4018c:9840069wayne_p<p>The establishment of OpenXPS is great news - the XPS technology is very impressive and I know a lot of people have worked hard on it for many years. </p> <p>My understanding of it is that WPF (and the .NET Framework) provides the underpinings.
