That's not really true. The Source interface does not have close to 
enough functionality to allow it to be used as input to a transform or 
validation or  anything else. The whole interface is two methods, 
getSystemId() and setSystemId(). There's so little useful functionality 
here one wonders why they bothered with a separate interface at all.

The only way engines work with sources is by specifically recognizing 
them as SAXSources or DOMSources. JDOMSource is a subclass of SAXSource. 
It does not really implement a JDOM-native source.

If validation and transformation APIs were really prepared to accept a 
Source as input, then I could pass in a JDOMSource or a XOMSource thatch 
correctly implemented javax.xml.transform.Source but did not subclass 
SAXSource or DOMSource and expect it to work.
