Hi Patrice,

    in case the first character of the name is something
    else than a letter [a-zA-Z]

I hate their standards.

    1) prefix the problematic cases with an 'impossible' construct, 

This feels like the slightly better of the two alternatives.

    for example a_q. 

How about g__? (two _ chars)  I don't think that can ever occur.
(g for GNU, although of course it doesn't matter.  Maybe x for XML, or s
for stupidity.)

@node .thing  -> g___002ething  (that's 3 _'s)
@node 005f    -> g__005f
@node g_      -> g_005f

    2) prefix with a letter and double that letter if it appears in the beginning
    of a node. For example with the letter q.

I don't like this one, because it will affect nodes (like "quote") which
don't have problematic names.  Better to keep the kludge localized,
seems to me.

Thanks,
karl
