Sorry, I'm probably getting confused more and more :-( I thought that
the the difference was from changing '-' from ET to ON, and not because
of A-F being AL and 6-9 being AN.

Attached is how my sentence looks like in BiDi Word.  The first two
paragraphs are LTR the last two are RTL. The 2nd and 4th sentences have
LRM between the space after ':' and the '02'.

Is this a bug/non-conformance?  I'm sorry that I use MS as reference,
but being CVS-challenged I have to wait to the release of FriBiDi.
