This element in the root pom for XP 5 is confusing:

<full.dist.product.release.version>8.0 Update 1.0</full.dist.product.release.version>

The only affect of that maven property is it ultimately drives a MANIFEST.MF attribute that in turn is read here:

https://github.com/jbossas/jboss-eap8/blob/EAP_XP_5.0.0.GA-dev-2/expansion-pack/src/main/java/org/jboss/eap/expansion/pack/ExpansionPackDependencyVerifier.java#L75

The value then is used to validate that the base EAP in use is at least the version specified.

The name of the maven property should be changed to better reflect its actual use, and an xml comment should be added to explain that.
