Arrix,
the link at Mozilla has no explanation either, anyway
I remember falling in to a problem with "originalTarget"
in which it pointed to a DIV not existing in the DOM.

After searching I discovered that "internally" they use
a DIV for the element construction and that DIV does
not exist in the DOM, and any tentative to access it's
properties will yield an error of type "access denied".

That's the reason I am concerned about it's use, it can
lead developers to use it and then complain, and
those kind of problems are hard to track down.

We should enforce users to use proper DOM specs
and try to avoid to give extra paths if those paths
are not offering extra functionality cross-browser.

Anyway tank you for being with us, your comments
and heads up are strongly appreciated.
