I don’t know that sequence is appropriate for this.  They are meant to
be for pass-by-value lists.

Is the issue here that you can’t use a base interface because then you
would lose some type specificity, e.g.

  interface Collection {
    attribute unsigned long length;
    getter any item(unsigned long index);

where you need to use “any” because you don’t know what the type of the
derived interface elements will be?
