:) What's the prize?
I am going to write about our closed source webapp, so if you are not
interested in that type of thing you do not need to read further.

Not simple, but doable. I doubt many people would have the patience and
suffer the hacks necessary (not too many...), though.
If you have simple data to enter (i.e. using a form) it would not be
too hard to use MSIE's MSXML SOM to do client-side schema validation.
Article-type content is bit more difficult, but you can still use the
SOM to only allow valid content to be entered. We have found that
editors who are used to using styles in Word pick up using our editor
fastest. Designers/artists who do not understand CSS are the worst (we
usually won't take them as clients).

We provide a ~wysiwyg~ view of the XML in editing, so it is better to
have some placeholder content in a new instance. I wrote ~wysiwyg~
because, of course, there is no true wysiwyg of content that is
separate from presentation. But users are familiar with MSWord style
editing so we try to provide something similar.

yep. For us, a page can contain multiple content pieces. The edit view
is transformed to provide the L&F of the final rendered page, but the
content pieces are xsl:copy-of'd in their appropriate location in the
page layout. The XML L&F is handled with CSS, for example:
c\:article {
display:block
}

sure, even more, be able to add/manipulate validly (is that a word?).

yep, also indexed by a search engine (Lucene)

For IE you need to have the XML start in a namespace, using a non-null
prefix, like:
<c:demo xmlns:c="boo">

Only IE for us on the client, until other browsers get a SOM. The
server is Linux and java.

yep.
