Bob, thanks for reading this over and commenting.
Before I address your questions / comments specifically, I should just say that I felt it was useful for people to re-familiarize themselves with this section as background for the F2F and the next phase of our work. As for the exact wording of this section though, I don't see us revising or reusing its language per se.

Needed Publication Properties was an initial attempt to define the properties that would be required in an EPUB dictionary publication in order to support the use cases in the original document. So it is outdated inasmuch as it doesn't reflect our recent discussions of priorities and concepts.
Structure and Semantics is simply a glossary of lexicographic terminology. We may incorporate some of these concepts into our semantics, but it's not a spec or requirement list.

That's true. But really, these are more like two different axes. While specialized subject dictionaries are generally monolingual, they can be bilingual as well (eg, a German-English scientific dictionary).
I'm not up-to-speed enough with ONIX to speak to its usefulness for this or for 2) yet.
On 3): yes, that's probably a better wording for it.
>4) I'd like to draw attention to the Use Cases document (rows 21-29). Row 21 includes a
>first stab at the atomic elements of a dictionary entry. Is it good enough?
Hmmm. I don't know that we should try to define what a dictionary entry must contain from a user point of view. The publisher determines the content, which may or may not contain a classification. (For instance, subject dictionary entries often do not have them--think of a dictionary of idioms, mythology, music, etc.)
Thanks for taking a stab at it. I'm looking at this more functionally--what is atomic element X in the context of an EPUB ecosystem? So my first stab at "dictionary entry" would be more like:
Dictionary entry: an organizational unit of a dictionary that contains one or more terms, and that can be rendered as syndication content by a reading system during word lookup
I'll try to reply to the remaining points soon.
