I don't see that as something a profile writer should decide
(I mean - whether to log or not, based on "logfile", but see below).

Although I don't think that logging (and thus specifying the log's file
name in the profile) is something that syntax should worry about, I
don't see why we couldn't add "logfile" as an optional attribute.

But it would be still nice to add a name, ID, or something. That way, if
"logfile" is not specified, we could use <stage>'s "name" to create that
file name (since, as I said above, I think that missing "logfile"
shouldn't be the reason not to log the stage, and it should be decided
by a user, from the parser, what is to be done).

It might seem like too much attributes - "name" (mandatory),
"description" (optional) and "logfile" (optional).

But nobody has to use "logfile", not even "description" in
non-interactive / non-graphical parsers (Perl implementation, nALFS -i),
so I think that's OK?
