Rizban is correct. Due to the innate enhancement bonus, the weapons and armor qualify for enhancements, and then you can apply up to +10 of other magical effects to the items. A relatively small bonus given that anyone with access to magical weapon and armor crafting will be shooting for a +1/+9 weapon with greater magical weapon tackled on it.
