I think that having document unchanged is non-goal. By having the same
information expressed in a two different ways means that it is very
likely that such information can diverge and you will have to decide
what takes precedence then.

I think that mapping from HTML+ITS to RDFa should strip all original
its-* attributes and global rules referenced by <link rel="itsrules">

Maybe you can use something different then NIF then. For example XPath
location of element that has its-* attached to it?

More I think about NIF which references location based on its character
offset (please correct me if I'm wrong) I think it's solution that will
not work. Even simple edit in an underlying HTML document will break up
all existing annotations.

ITS 1.0 is used to attach data categories to element and attributes. So
anything what will be able to address DOM nodes of type Element and
Attribute should work. Supporting just DOM Text node is not necessary as
there is no corresponding XML representation.
