semantically i completely disagree... ;--)
in both cases the written pitches ARE transposed (sound) down an
octave, as explicitly indicated by the 8_clef in the version, and the
8vb indication in the second. indeed, the whole raison d'etre of those
indications is to show that the displayed pitch is transposed an
octave lower.
in the case of a 'transposing at the octave' instrument such as
piccolo or double bass, the clef change or 8va/b sign is implied and
simply omitted as a convenience.
agreed the sounding pitch in each case is the same, but this is a
notational, not a sounding issue.

Hi all,
Even more to the (semantic?) point, the following two are IDENTICAL
with respect to pitch:
\version "2.11.37"
\include "english.ly"
musicClef = \relative
{
\clef "treble" f e d c
\clef "treble_8" bf a g f
}
musicOct = \relative
{
f e d c
#(set-octavation -1) bf a g f
}
\score
{
<<
\musicClef
\musicOct
>>
}
In NEITHER case are the PITCHES "transposed" in any way -- in both
cases, the PITCHES are identical... and the same as "the original".
What's happening here is that, in Version #1 (the clef change) we're
explicitly showing that the notation is in a different clef, whereas
in Version #2 (octavation) we're using a shorthand to transpose the
CLEF ITSELF (while leaving the pitches exactly where they are)!
Therefore, I suggest something like "Clef transposition and
octavation", or something like that, so that it's clear that the
PITCHES are not being transposed in any way.
Cheers,
Kieren.
