There are some area which is more insteresting
- Let extension get notified when the inkscape doing some jobs, such as * Load/Save file * Print * Change document property
Yes, those are supported via the 'UI' DOM and DOM Events. And events such as the change document are already defined by XForms.
- Intercept the procedure of modifying the object. Allow extension to disable the action.
For example, protect some objects generated by the extension from deleting.
Yes, this two is completely supported via DOM Events. The order, canceling, overriding, etc. has all been worked out and refined. It does have a few shortcomings, but our current dual-tree model has even more (look to the bugs with layer renaming, etc. for examples of those problems)

"capture" and "bubbling" are the concepts you're most likely interested in.
Do you means XForms can do or Inkscape had worked like it?
