In Reading and Composing Indians: Invented Indian Identity Through Visual Literacy, the authors write: "We use the term visual here in juxtaposition to textual, although visual elements have textual features and supplements, and often text has visual elements and supplements...." (p. 48) They mention what was discussed at the 2001 Conference on College Composition and Communication, in regards to issues and directions in visual rhetoric, and one of the topics was the need for a shared vocabulary for discussing visual rhetoric, although the complexity of visual language prohibits this.
I would add that, the complexity of visual language precedes the ability to understand, situate, translate/interpret visual language firstly; this first step is what makes visual language spatially prohibitory, or a shared vocabulary for discussing visual rhetoric effectively. Another issue would be the post-modern, rather post-historical situationing of subjectivity, identity. Otherness has a new meaning; no more alterity; the Other is rather a reflection of the subject's Void, in an absence of meaning or any multiplicity of identities.

How Meaning is Historically Situated, and how power relations work into making "meaning" fluid.
