title: XSLT 1.0 How to extend with fn (function namespace)
body: <p>I was wondering how I can possible extend XSLT 1.0 so that I can use functions from fn function namespace at <a href="http://www.w3schools.com/Xpath/xpath_functions.asp" rel="nofollow noreferrer">http://www.w3schools.com/Xpath/xpath_functions.asp</a></p>
  
  <p>I was just told that the system is using MSXML XSLT processor from now on. All my stylesheets were written in 2.0  ... So now I'm stack, nothing is working and don't know how I can use functions for example from fn namespace. </p>
  
  <p>I was wondering whether it will be possible to extend XSLT 1.0 somehow, because I use lots of those functions. Or what do I do now? I'm absolutely lost and frustrated.</p>
  
  <p>Would really appreciate any help!</p>
  
  <p>Thanks a lot!</p>
