Source port with default fallback value?


I was wondering whether it was possible to create a p:pipeline that 
works both when a "-isource" argument is given on the command line and 
when it is not.

The logic should be like this:

* if a URL is provided on the command line using `-isource=foo.xml`, 
then the document at that URL is used as the source document;
* if no URL is provided, then the document `default.xml` should be used.

How can I obtain this behaviour in XProc?
