Firstly, this question has nothing to do with XSLT.

Secondly, references to environment variables such as $PROJ_HOME are
replaced by the contents of the variable only when you are executing a shell
script, not when you are running software such as an XML Parser.

The correct mechanism to use here is a relative URI.
