apart from the very real semantic problems which Stuart gives (which I think are acceptable if processsing a <pb/> like this,

 <p>I have endeavoured in this Ghostly little book, <span
        style="font-style:italic">to raise the Ghost</span><div
        style="float:right">a phantom</div> <span
        style="font-style:italic">of an
