Hi Guillaume,
The problem is reported correctly as an error, because actually a keep 
constraint is dropped.

Well, you are getting an output file that does not match the input file 
in terms of the strict processing rules - the XSL FO Recommendation. The 
result matches an input that is similar to the one you feed XEP with, 
but differs in a missing keep constraint.

Numeric values for @keep-* are not supported 
(http://www.renderx.com/reference.html#ftn.keep-property).

You can make it really quite if you add 2>/dev/null or specify 
NULL_LOGGER via XEP API.
