Suggestion:
Allow the enchantment description key to be in the format "enchantment.[MOD_ID].[ENCHENTMENT_REGISTRY_NAME].description" as well as the current supported format of .desc. This will allow any mod that has JEI Enchantment Info compatibility to automatically be compatible with Enchantment Descriptions.

I've implemented partial support for it in 7.0.7. I would recommend that mod authors continue to use the .desc suffix though. This key format has been widely used by several mods and dates back to roughly the same time enchantments were added to the game.
