You cannot assign an attribute to an individual element of any array. The behaviour for indexed arrays is described in the manual: "declare -a name[subscript] is also accepted; the subscript is ignored." In the case of a previously declared associative array in the current scope, one might argue that bash should throw an error instead. I think what you're seeing is bash taking a "reasonable default" instead of throwing an error in response to a nonsensical assignment. Note that ksh93 is different in some respects because it allows "nested variables".
