The Advanced Player Guide introduced Elemental Arcane schools, and Chapter 5 listed the spells that were available (at the time of publication) to be used as bonus spells for each element. However this list does not appear to have been updated, since the APG despite a wide range of official spells being subsequently published such as those in Advanced Class Guide and Ultimate Magic. For example, Stone Discus (pg 196 of ACG) has a [earth] descriptor, but is not on the list for an earth elementalist.
Is there any intention to update this list in future products or have I missed one in which it has already been done? Or was it the game designers intention that a relevant descriptor would lead to inclusion as an official bonus spell for each of the elements. (My DM is OCD about sticking to canon - frustrating sometimes but he is the only game in town currently).
