sum of out-transition probabilities != 1.0 ?

Hello SRILM users,

how is it possible that PFSGs, generated with ngram-count and
make-ngram-pfsg (default discounting) have nodes whose sum of the
probabilities of all outgoing transitions do not sum to 1.0 (but, e.g.,
1.1)?

I thought this was an important constraint, but maybe I am missing some
theory...

Regards.
Matthias
