node names in Documentation/user/notation.itely ?

[Graham Percival]

What's the new naming convention for nodes?  For example, I see:

@node Harmonic notes, , Other instrument specific notation, Other 
instrument specific notation
@node Popular music, Orchestral music, Tablatures, Notation manual
@node Chord names, Chords mode, Popular music, Popular music

but later on in the manual I see the normal ones again:
@node Orchestral music
@node Rehearsal marks


Were some changes only made to some sections?  Or did
somebody's text editor go berserk and they accidentally updated
CVS with those unintentional changes?

Cheers,
