Clients are free to call the WC lib. They don't want to receive pre-formatted
descriptive text from it. I think they want to receive structured data which
they can interpret themselves in order to make decisions on it, and to present
the data to the user in any way they choose. If we think it is worth giving
them the ability to convert it to "standard" or "default" human-readable text,
we can provide a client-layer function to do that.
It's the client library's job to provide a client-oriented view of both the WC
and the repository and the interactions between them. Although conflicts happen
only in the WC, I still think it is the client's job (aided by the client
library) to provide a higher-level view of what goes on in the WC, and the WC
library should not try to do this presentation of data itself.

I'm not proposing duplication. The WC lib should manage the WC and supply data.
The client lib should help the client to process and present that data.

I'll reply separately about this topic of how to display the information.

Yes. Issue #3156 <http://subversion.tigris.org/issues/show_bug.cgi?id=3156>.
I've just added the keyword "tree-conflicts" to it.

This is related to the philosophical question, "In a tree conflict, is it the
victim that is in conflict, or the parent that is in conflict, or both?"

Well, I wasn't very clear about what this section is about. Actually, I meant
this section to be about selecting and/or merging the two conflicting changes,
and I meant the following section "[RESOLVED]" to be about telling Subversion
that you have done so. Interactive resolution does both of those things. I'll
change it so there's just one section about resolving.

I mentioned both of those issues.

I'll start a new thread on that.
