context + values, same old story.
what is the context and how (techniques used, convetions of form - this is where the newspaper htings like lead, tone, voice, layout etc come in) is it portrayed. what are the inherent values of the text and how (techniques again) are they conveyed. how does the context effect the values and the portrayal of both (audience, purpose).
these are the three things you TYPICALLY (you can still get left field questions) need to adress in and analysis of a text. anyway, its a good place to start.
