Dear Alison,
I read your comments and I think I must clarify a few things. The terms "digital skills" and "digital or technology literacy" are not quite the same, with the first being more specific  and specialized. Also the "data-driven" characteristic is rather vague. Perhaps you wanted to say "information-retrieval skills from vast repositories", which is something more tangible.
Anyway, e-leadership is a rather new term which needs time to mature to a rigid description.
