WildFly FP doesn't depend on the jakarta-ee10 criteria (at least in my example), it depends on the jakarta-ee criteria. A feature-pack can choose what are the criteria it needs from its dependencies. Got it, a FP will inherit a criterion from its parent but only this criterion, not the other ones that could also provided by the parents.

This would look like in the wildfly-feature-pack-build.xml (file to build feature packs). The syntax of the allows family is <family>+criterion[+criterion]: <dependency group-id="org.wildfly" artifact-id="wildfly-ee-galleon-pack" *allowedFamily="wildfly+jakarta-ee+deployment"*> Maybe the syntax should distinguish between the family and the criteria. Something like “family:crit1+crit2”?

Yes that is correct in your provisioning.xml (or WIldFly Maven Plugin configuration) you would have (image WF 39.0.0.Final): <feature-pack location="org.wildfly:wildfly-ee-10-feature-pack:39.0.0.Final"/> <feature-pack location="org.wildfly:wildfly-galleon-pack:39.0.0.Final”/> Naming is hard but it’s confusing that a *new* feature pack named "wildfly-ee-10-feature-pack” would appear long after WildFly supports EE 10 and when it moves to EE 11…. Maybe "wildfly-compat-ee-10-feature-pack"?
