I did not check the latest po4a, but in version 0.16.2, afaics, nsgmls 
returns 1 because the data po4a gives it is not valid Sgml code. The 
problem comes from the {PO4A-beg-xxx} items that Sgml.pm inserts to deal 
with the conditional inclusion mechanism.

So I guess one way to avoid it would be to not use conditional inclusion 
in the original document but that's quite restrictive.
