In your point 3, surely the alterations take place
*before* the model is saved i.e.
form.load(model);
form.showForm("uri");
//do the DOM manipulation of the form/model(?)
form.save(model);

OK, I'll bite
1) At the moment, NO released version of Cocoon, up to 2.1.6, has
support for binding a field (HTMLArea or otherwise) to an XML document
or to check that the contents of a field is well-formed XML. If you
want that, you must write some code yourself.
2) The fact that you are using the normal "binding forms to an XML file
approach" does NOT rule out the possibility of handling some fields
_outside_ the binding framework, i.e. by hand, as I hinted when I
wrote:
"You could insert it right after the call to form.showForm(). You
could, for instance, use the forms binding framework for all fields of
the supported datatypes, and manually retrieve and parse just the HTML
fields."
3) Actually, there is no such thing as a "binding forms to an XML file
approach" in CForms! The binding is, IIRC, to a DOM document, which
fits quite nicely with the fact that my class returns a DOM.
If you want some pseudocode, how about this:
var model = .... // Some DOM object
form.load(model);
form.showForm("uri");
form.save(model);
var html = form.lookupWidget("/htmlArea).value;
var dom = HTMLParser.parse(html);
var parentNode = model.someDomApiCall() // Use the DOM to get the point
in the doc where you want to append the HTML
var newNode = model.importNode(html, true); // Import the HTML
parentNode.appendChild(newNode);
The last three calls are straight from the DOM API.
