While there are some question-askers that confuse literary interpretation with authorial intent (dealt with elsewhere), there are also some who ask specifically about authorial intent on a specific topic, like this question.
Do we need a tag for this? A tag might help to ensure that these questions are not misconstrued as questions about analysis divorced from authorial intent, and might also prevent answers that do not address the question asked by the OP.* (This suggestion assumes, of course, that the original poster understood what they were asking, and made certain to indicate the precise nature of the query in the body of the post)
I don't have a specific wording in mind for the tag; authorial-intent might work, but if you have other suggestions please do post an answer.
*Should this be termed the "unintentional fallacy"? :P
