I think if there was a wizard style create project, they'd be happier.
If nothing else, create the DataDomain, DataMap, DataNode for them
(ask for the values and explain what each is used for). Maybe ask a
few things like PK generation strategy, etc, too.

Yeah, I know we've talked about it before, but I'm not the only one
that likes the idea. :-)

I got that information second-hand and can try to glean more details
later as to why he ditched the modeler. If some people are just
naturally wired to want to edit XML by hand, we can't do much about
that. However, if there were deeper issues, it'll be good to know
them. I'll try to find out more and report back.

I'll ask him for examples.

I can talk to him again, but he even went to the online docs and tried
to figure it out and still wasn't able to do the mapping.
