Add an attribute with static value with xslt

Question

I need to add an attribute with a static value to all nodes of a specific type in an existing xml file using xslt. Basically something like this:

Answer 1

 
  static string
  
 

(or something like that) inserted into an XSLT that does an identity transform (see http://www.dpawson.co.uk/xsl/sect2/identity.html) should do the trick for you.
