Target is not necessarily a specific segment, but we say it is

Describe the problem

In the section titled "Subset of the Web Annotation Data Model" we say:

The Target of an EPUB Annotation is the content being annotated, which is a specific segment in a document within the EPUB package defined by its relative Source URL and a Selector.

However, we do not require the target to be a specific segment in a document, unless we are including the entire document with no range specified as a "segment in" that document. I am actually not sure why we need to define target here at all? There are a lot of nuances (for instance, I am not sure from this definition if selector is required), and this is just a list of changes from web annotations, which is really only interesting to people that know what is in web annotations, and hence are likely aware of how target is used.

Describe the fix or new feature you propose

I propose deleting the second sentence of this bullet point.

We'll discuss this at the next call, but I agree with you: this section lists the constraints applied in this specification, relative to the W3C Annotations Data Model: we don't need to add definitions there.
