If there is no such element, the attribute is placed on an empty <code>css:_</code> element inserted as the last child of the last preceding inline box (in the same block). In the former case, if the attribute is moved to a <code>css:box</code> element that already has a <code>css:string-set</code> attribute in the input, the 'string-set' declarations are prepended to it.</p> </p:documentation> </p:output> </p:declare-step>
