Gary,
XMLResource.OPTION_KEEP_DEFAULT_CONTENT. You'd set it as a save option
in your resource factory. Newsgroup search is quite handy for finding
previous answers to questions like this:

Sorry but,

Where is OPTION_KEEP_DEFAULT_CONTENT defined and where do I put it in
my code to alter the default behavior.

Yes, when eIsSet is false for a feature it won't be serialized. But you
can use this option to alter that behavior:

I'm not sure what you mean by unchangeable. If you serialize it, I
assume you expect it to be read in again and hence for it to be
changeable...
<br>
<blockquote type="cite">and have it serialized to the document.
