Andy,

XFA's are a best practice, not required anywhere.  The reason behind XFA's
is modularity so that a fuse can be reused without having to alter any code
inside of the fuse.

You could just as easily hard code any cflocation calls directly into the
fuses, it just makes it difficult to reuse the same fuse elsewhere in the
same circuit.

Now that I find interesting. Even if XFAs are not part of the core (the
"framework") I always thought they were a part of the core methodology.
Isn't it true that you  always aim for this ...

A) The only thing that references fusefiles is the switch in the same
circuit.

B) The only place that fuseactions are referenced explicitly is in a
switch file (either local circuit or remote).

Aren't XFA's essential to implementing that principle ?

Andy.
