Rather than globally mapping a class to an alias, it would be nice to make a mapping contextual; that is, to make a mapping conditional upon parent nodes. For example, if my class has a list of, say, usernames, the generated (and expected) XML for it might look like: ... <users> <string>Tom</string> <string>Dick</string> <string>Harry</string> </users> ... In this case, it would be nice to alias java.lang.String as "user" when contained by "users", resulting in: ... <users> <user>Tom</user> ... Globally aliasing java.lang.String has some obvious drawbacks. I looked through the code and it looks like this would be a rather large undertaking, but thought I'd toss the idea out.
