event listeners and ids with Range cloning methods

A couple of questions about the Range for which I'd
appreciate confirmation or clarification:

- should cloneContents clone eventListeners?  Based on
behavior for cloneNode and the Events spec., I would
guess no.  If it did, this raises issues for
partially-selected nodes.

- should extractNodes maintain eventListeners? If this
method is considered cloning, then I would guess no. 
If so, then I see issues with extracting
partially-selected nodes.

- should cloneNodes and extractNodes clone attributes
that are of type id, or other attribute types that
expect uniqueness?  I'm guessing that it is allowed
since I don't see any exceptions for validity.  If I
am correct, what is the user of an implementation
recommened to do to use the Range without creating
invalid markup?  For an html document, I could see
removing id attributes from nodes in the cloned
fragment before adding it to the document 

Thanks,
Dylan Schiemann
