Instead, I get an error "Cannot write more than one result document to the same URI".  My guess is that I'm having trouble with the scope of $filename, inheriting it's value from an earlier iteration of the template and, since variables can't be reset, the new value sent to it is ignored.  Is that true? and how do I get it to change?

Here you write to status.xml and then

here you call the template again, resulting in a further attempt to 
write to status.xml again.
