Looks like the answer is no.

Yes, you can write your own methods and have them marshal/unmarshal text
in your XML. This would probably be useful for you.
The only thing to note is that since you cannot describe the constraint
in schema nicely, validation won't work to detect errors; your
conversion methods need to do it.
See the specification about <javaType parseMethod="..."
printMethod="..."/> for details of this feature.
