[jdom-interest] Attribute defaults

[rpcee]

I guess the type information should not generally be held in Attribute, 
Element, etc because it will expand the interfaces and because DTDs schemas 
RELAX etc will all have a different view of metadata. I don't know if default 
value counts as metadata. If you know what attributes you want to omit if they 
have the default value perhaps you could override printAttributes() in 
XMLOutputter.
