I just run the example with Xalan and got the following error:
---------
file:///C:/TextWidthTest.xslt; Line #17; Column #105; XSLT Error
(javax.xml.transform.TransformerException): java.lang.NoSuchMethodException:
For extension function, could not find method
org.apache.xpath.objects.XNodeSet.new([ExpressionContext,] #NODESET,
#BOOLEAN, #BOOLEAN).
----------

Maybe you use a Xalan release which is incompatible with your user class,
or you have two incompatible Xalan releases on your class path. Xalan's
internal interfaces changed over the course of time.
You might get more competent help on Xalan's user list. Mail to
 xalan-j-users-subscribe@xxxxxxxxxxxxxx
for subscribing.
