Section 2.1.3.2 says:

           ii.  If LSB(fn) is not set, then right-shift both fn and sn
                equally until either LSB(fn) is set or fn is 0.

It should say:

           ii.  If LSB(fn) is not set, then right-shift both fn and sn
                equally until LSB(fn) is set.

Notes:

This even case can happen only when fn == sn > 0, which means that the shifting loop always terminates with fn odd (and hence non-zero).

Suggesting that fn == 0 can happen is confusing, since in this case the preceding update of r, using a path element as *left* sibling, makes no sense. Not sure if it would be helpful to also add a comment explaining why the loop terminates.

The same correction applies to 2.1.4.2, algorithm step 6.b.iii.
