Greetings. 
 
I have a Java method I want to call from my XSLT script (I am using Saxon of course).  I use the following code: 
 
   <xsl:variable name="ignore" select="foo:bar()"/>

The bar method doesn't return anything of value, it really is a void method that I have returning the dummy value 1.  But the xsl:variable method is optimized out since I never use the returned value. 
 
What is the syntax to force the XSLT engine to call foo:bar? 
 
Thanks in advance.
