No, I think you are right. The primary issue with motivation is that it
defines the role of the body within the annotation. I think we want to
reserve type to represent something structurally specific to the
annotation, e.g., highlights. In the highlighting use case I might have a
"Highlighting" motivation but, we could just as easily consider that all
highlight annotations do not have bodies but do have CSS instructions. This
is a case where we can get some significant mileage out of sub-typing
oa:Annotation with an oa:Highlight (or somesuch...there might be other
"bodiless" use cases. As once we see either the sub-type or the motivation
then our software can make some assumptions, e.g., do not expect oa:body,
do expect oa:style; if this is not the case then not a valid annotation.
You can't realize that type of validity checking with motivations, and in
fact with the glaring exception of highlighting (and maybe one other
thing...) motivations don't help use validate.

Regards,

Jacob
