I think (I may be wrong) that all Jeremy is asking for is that nALFS2
require you to specify what the compression method is for the package. The 
other information such as local location, download location and optional
will still have to be supplied. Just specify the filename and :-


The downloading <reference> part could have a preference, say
to search for from the url and if it can't we found try .tar.gz and so on. 
Same with the <archive> element. It could strip of the filename portion and 
compare the extension with .tar.bz2, tar.gz e.t.c and use the appropriate
decompression. All this relies on the digest not being checked though and 
should only work if digest checking is disabled which I don't see a big deal
