Re 2: More role-related potential changes to Web Annotation Data Model

Having looked at the text again, I question came to my mind. Let us suppose we go with Proposal 2. What that entails is to define a subclass of EmbeddedContent called EmbeddedTextualBody. However… the current OA draft specifies oa:EmbeddedContent in a section entitled "Embedded Textual Body"[1] and the class is used only to 'qualify' texts with media types or languages, etc. Why would we need a separate oa:EmbeddedTextualBody? Why isn't it simply enough to have and use one class (whether its name is EmbeddedContent or EmbeddedTextualBody is besides the point)?

We followed a table of contents based on roles.html document, but if augmentation with additional use cases is needed, feel free (just don't delete or renumber any of the existing items in Table of Contents Section 3).

But a couple of issues summarized in Section 3.2 of the roles.html [1] document were not formally resolved, specifically, the 'further considerations' discussed in:

> At this point, Paolo and Rob are already working on the next update of the Web Annotation Data Model, so it'll be up to them and Frederick whether to revisit these further considerations now or wait until after the next iteration of the Data Model is ready, or at least until TPAC. It may be that the discussions the WG has already had and the process of updating the model will clarify things to such a degree that we don't need to revisit these issues during one of our upcoming calls/meetings – in which case the new page will just help complete the documentation of the hasRole discussion we had over the summer. But if more guidance from the WG on these further considerations is needed at this time, the page is available to facilitate that discussion.
