"WYSIWYG Writer" Friendly Editing Tools

One of the issues 
facing the writing group with which I work is finding tools that are "WYSIWYG 
writer" friendly so that the majority of writers in the group don't immediately 
give up on writing documentation in XML because "it looks ugly", "I don't know 
what it will look like when I'm done", "it looks too much like code", "there is 
no support for automatically keeping track of cross reference anchors", and so 
on. There is a long history of Frame Maker use in the group and an ongoing 
effort to make Frame Maker, using a template that looks and feels exactly like 
our old unstructured Frame Maker template, edit Docbook XML. The effort to make 
Frame Maker work as a Docbook editor has gotten close, but  there are a 
number of things it just cannot handle yet and I'd much rather spend my time, 
and that of the other writers, getting comfortable with a lighter weight tool 
that actually is built for working with XML.

Does anybody have 
suggestions for either an XML editor that is close to WYSIWYG and supports text 
entities? XXE does a great job with WYSIWYG, but does not support text 
entities.

Suggestions about 
how to break the dependency on WYSIWIG would also be greatly 
appreciated.
