COCOAisms vs DOMisms vs CoreFoundationISMs

I'm not sure if this is covered anywhere in the documentation, but are the following assumptions correct?

1. When a DOM method returns a newly created object, that object will be an autoreleasing object.

e.g

- (DOMNodeIterator *)createNodeIterator:(DOMNode *)root :(unsigned long)whatToShow :(id <DOMNodeFilter>)filter :(BOOL) expandEntityReferences;



2. Where the DOM object has a detach method (DOMNodeIterator and DOMRange), that method does not need to be called (assuming that the autoreleasing assumption is correct), but it can be.

3. All of the DOM classes inherit from DOMObject and that says it conforms to NSCopying. I am guessing however that calling [someDOMObject copy] is not going to produce a standalone copy of many object types. As such, unless there is a 'cloneXXX' method declared for the class such a standalone copy cannot be produced.
