Very. Remember, an XSLT stylesheet is a program. It may loop. It may 
recurse. It may go back and reconsider data from sections of the document 
previously processed. And its results are dependent not only on the size 
of the input data, but on its structure and details. There really is no 
good way for the processor to guess progress on any but the most trivial 
stylesheets.

Try writing progress indicators into your stylesheet, using <xsl:message> 
or your processor's extension mechanisms. That'll both give you a good 
idea of how hard this is to automate, and will be more likely to give you 
useful results.
