From an extension _element_... I don't think so.


From an extension _function_, yes. If the returned value is not an 
instanceof one of the types called out in the mapping table (
http://xml.apache.org/xalan-j/extensions.html#ext-functions), it will be 
returned as an object reference. Generally you can't do much with those 
except store them in variables and/or pass them as parameters to other 
extensions.

If your returned value *is* an instanceof one of those types... The best 
suggestion I can give you is to set up a wrapper object which does not 
implement those types, return the wrapper, and have whoever is using the 
value unwrap it again before accessing it.
