Hi Leif,

Thanks for checking this.

Fixed. Thanks.

That part of the spec text is somewhat dependent on the outcome of alt
ISSUE-31 question two [1]. For the time being, I made a note to that
effect in the sample spec text [2]. It can be adjusted after ISSUE-31
is decided. longdesc needs to be inserted but just how is affected by
the spec text for alt.
