Hi, Maciej-

Thanks for your comment. Chris has answered most of this email, but there
was a further change that I wanted to inform you of.

You're right, this is clearly a duplication and a mistake. We have corrected
the second point (for bare name fragment identifiers) to indicate that if
the element is found, the viewbox is adjusted to center on that element.

If after reviewing the wording in the next public draft of the spec your
concerns are not satisfied, please respond promptly.

Thanks-
Doug, on behalf of the SVG WG
