WEIBEL also made the point that the AAP tag sets, while not excessively prescriptive, offer a common starting point; they do not define the structure of the documents, though. They have some recommendations about DTDs one could use as examples, but they do just suggest tag sets. For example, the CORE project attempts to use the AAP markup as much as possible, but there are clearly areas where structure must be added. That in no way contradicts the use of AAP tag sets. SPERBERG-McQUEEN noted that the TEI prepared a long working paper early on about the AAP tag set and what it lacked that the TEI thought it needed, and a fairly long critique of the naming conventions, which has led to a very different style of naming in the TEI. He stressed the importance of the opposition between prescriptive markup, the kind that a publisher or anybody can do when producing documents de novo, and descriptive markup, in which one has to take what the text carrier provides. In these particular tag sets it is easy to overemphasize this opposition, because the AAP tag set is extremely flexible. Even if one just used the DTDs, they allow almost anything to appear almost anywhere. ****** SESSION VI.

Having attended several sessions in an effort to gain a sense of what people did and where copyright would affect their lives, PETERS expressed the following cautions: * If one takes and converts materials and puts them in new forms, then, from a copyright point of view, one is creating something and will receive some rights. * However, if what one is converting already exists, a question immediately arises about the status of the materials in question.
