This might be a numpty question but here goes. I know that I can pass
parameters to an XSLT stylesheet, but can I do this in reverse - set the value
of the parameter within my XSLT stylesheet and then access the assigned value
once the transform has finished? What I had in mind was to use the
javax.xml.transform.Transformer object in my calling program and pass it an
empty string using setParameter(), assign the parameter a value during the
XSLT transform and then call getParameter() after the transform has finished?

The reason I'm asking is that I have an application that receives an XML
datastream through a servlet. The servlet formats the XML into a
"user-friendly" text file via the Transformer class and attaches the result to
an e-mail. I've now been asked to include data from the XML document into the
title of the e-mail.
