Problem of ref target pointing inside a same page (Knesebeck, DR, FR, 39)
Problem when clicking on the ref taget here in Knesebeck : it opens a page with "null" ; it should not open a new window since the target are inside the same page:
<add place="above" xml:id="addp79_1a"><ref target="#addp79_1b"><hi rend="superscript">+)</hi></ref>
<add hand="#Knesebeck" place="bottom" type="asterisk" xml:id="addp79_1b"><ref target="#addp79_1a"><lb/>+
