Hi Barthelemy,
thanks for your interest in EMF Facet features.
Unfortunately you may attach only one Query condition to one conditional feature value(FeatureValueCase.condition multiplicity is [1] in customization metamodel).
I do not know if it may work in your use case : as a work around you may inverse conditions. Considering A AND B = NOT(NOT A OR NOT B), you may specify (NOT A) as a first FeatureValueCase and (NOT B) as a second one with some "default/blank" value, and put your wished feature value (for A AND B) directly on the feature ("edit feature value..." button).
Else, you will have to write some agregation Query which calls your two leaf queries, and use it as a condition.
You are free to fill some bugzilla https://bugs.eclipse.org/bugs/enter_bug.cgi?product=EMFT.facet for asking the enhancement.
Regards,
Fabien.
