RE: Unknown variables in XPATH (2.0)
# # Yes, but that isn't what is wanted by the user in question. # It's a case of boolean-valued environment variables, to indicate # certain products are installed. Most people don't bother to define # such an environment variable on their system, to indicate they haven't # installed the product, so false() is the natural default in this case. It would be much better to meet that requirement through an extension function xx:is-installed('product-name'). Michael Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
