xpath environment variable
# 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').
