Yes, in that characters like 0x0 are illegal in XML,
everywhere, including text, attribute values, comments
and even processing instructions.

Also note that rules for detecting such illegal
characters are different depending on whether you are
parsing an external document (from file, network), or
building a document using JDom. In former case it's
not JDom that verifies legality of characters, but the
underlying parser (SAX etc); in latter case it should
be JDom. However, I think JDom is bit more lenient
than other tree models, like XOM, in that by default
you may be able to sneak in strings with illegal
characters.
