Stephanie,

Just trying to understand the use case here.

What you are doing in this example is pointing to so-called complex
content, i.e. an element containing "stuff" other than just text.

Right now, XForms disallows that: you can only point to elements
without nested content, or attributes.

So the question is: what do you do with that content, both ways:

* when reading from the instance to the control
* when writing to the instance from the control

What's your algorithm for those operations?

Right now if you bind a nodeset to a textarea, it will display all of the contents of the nodeset, but I want, upon changes to the nodeset in the textarea, that the appropriate node be updated in the instance. That doesn't happen now - it just gets reset to the original instance's data.
