utterances; UI

[BestATN@aol.com]

1) utterances are the top level of loglan grammar and subsume everything that is loglan under that name.  relevent?  maybe not, since lojban uses "text" instead.
2) i consider a sigh to be more an utterance than, say, a smile or a frown (though both have meaning), and a LOT more than a burp or belch (even though these are audible).  as to how to spell a sigh, i just use *sigh*.     *sigh*
3) as for the truth values of UI, i side with the no-truth-value-ers, though i can see the point about smoke lying.
