+As seen, ScrollblockCellLinker is the class implementing CellBuoyViewLinker,
+and when asked to make links for a given cell, it looks for both
+enfiladeoverlaps (transclusions) and xu links. Different types
+of pagespannodetypes are used for these: for transclusions seeing
+the whole original pagespan scrollblock is good, and for xu links,
+seeing only the anchor part of the target is good.
