Notes on the Saxon implementation
As well as the standard system properties defined in the XSLT namespace, the Saxon implementation will return the value of a Java system property (e.g. as set using -X on the Java VM invocation) if the name is unprefixed. It does NOT return the values of operating system environment variables.
More specifically, if the argument is a name in no namespace,
that is, if the name is unprefixed, then the name is taken to refer to a Java system
property, and the value of that property is returned if it exists. For example, on
a Windows platform, system-property('file.separator') returns "\".
This can be used to obtain information from the environment, and is especially useful
in conjunction with use-when conditional compilation.
