+%    Some code (e.g., font handling coming from Con\tex{}t) behaves strangely
+%    with \verb+\attribute0+. What is more the font loader allocates its own
+%    attributes in the range from 127 to 254. Since there is plenty of room
+%    here, it doesn't seem bad to skep a few items in order to avoid clashes.
