Change processing expectations of ulink?

Should we change the processing expectations of ulink to indicate that
an empty ulink should use the contents of the url attribute as the
hot text:

<ulink url="foo"/> = to html =>  <a href="foo">foo</a>
                   = to print => foo

                                        Be seeing you,
                                          norm
