    Thanks for the clarification.

    I totally see your

    OTOH, my reasoning is that, *I* (so it's not as if EM is doing
    something I didn't requested) did select the prototype and thus I
    expected it to switch my attribute to using the prototype even if that
    means resetting values. In fact I actually expected it to reset the
    attribute so that it exactly matched the prototype. But in this case
    it did exactly *nothing* (?) which is totally misleading and puzzling.

    When you speak about "overriding" settings I would expect that this is
    again something *I* would do *after* specifying the prototype.

    Also, specifically for the external type, I'm wondering what would the
    benefit of using a prototype with an external type different from the
    one defined in the prototype? For the other settings the it's obvious
    that preserving their value may prove useful.

    Will do that.

    Thanks
