[NTG-context] more register questions!

Hi, making wonderful progress on my registers and translating from xml. There is one thing I can't figure out (and I or some other good soul may have asked in the past...). Is it possible to mark occurrences in footnotes? Ideally, the entry in the register would look like p. 100\high{20} to show that the term occurs in note 20 on p. 100. But if that's asking too much, I would be content with applying a processor (say, italic) to these register entries. From the looks of the tuc file, Context doesn't appear to "know" that a register entry is within a footnote. But Hans never ceases to amaze me, so maybe there is a way (short of applying special markup to these notes in the source)? All best Thomas
