Thanks, that makes the compiler happy! 

For other newbies, I also needed to either: 

import the class: 
         import javax.xml.transform.TransformerFactory ; 

or
specify the class fully:
          javax.xml.transform.TransformerFactory transFact = new net.sf.saxon.TransformerFactoryImpl();


Now, to execute it, and find out what the XSLT 2.0 standard requires from my turgid transforms.
