Decoration is fine if you have the tune that definitely belongs to the text; otherwise I'd guess that a generic tune may be safer.  It's probably a good plan not to rush into posting things that have the right title but may not actually match up with the text on the DT.  I've been spending a good bit of time trying to fit words (so often posted inaccurately by well-meaning people who didn't understand the idiom) to what ought to be the right melodies, and having a hell of a time of it!  Hey, just because I'm a bit anal-retentive about that kind of thing doesn't mean you have to be.

By the way, re. AILENN DUINN filename[ AILNDUIN  -I have the music for this version in Bruce Campbell's Oran nan Gaidheal (Gairm, 1987), but it's in Tonic Sol-Fa, which I can't make head nor tail of.  If anybody round here can read it, I'll happily send a scan of the page...There's a tune in Kennedy, too, but's it's a different version (Flora MacNeil) which doesn't fit the DT text.
