Eh?!?!  You want to tell people to put articulation and dynamic
marks after the duration, before they've been told how to do
articulations and dynamics?  Remember that the idea is to give a
general:
@var{pitch} @var{dur} @var{other}


No, you should.  This thread has nothing to do
with articulation and dynamics.  It is to to
with the relative order of octave marks and
durations.


Yes, the *initial* concern was over the relative order of octave
marks and durations.  My *current* concern is that if it's
possible for people to get confused over
c4'
then surely they could also get confused over
c'\mf4


As often happens with these threads, the initial
point can easily get lost.


If so, there's two options:
1) give a general explanation of pitch-dur-other.  In addition to
that order, explain that the order of other doesn't matter.
2) give an explanation of pitch-dur, then later on explain
pitch-dur-other (or maybe note-other, or something like that)

I thought that #1 would be best, but if you'd rather go with #2, I
have no objection.


I think we need both.  Let's clear up the order of
octave marks and durations as I suggested in LM 2.1.2
with Simon's help.  Then, because the order in which
items may appear in a notation element is quite complex
this needs to go in the Notation Reference, if it
is to be anything like comprehensive.  Carl's
parser grammar will be useful as an appendix, but
something along the lines of the note Trevor Baca wrote
some time ago to explain the permitted order of items in
a notation element would be suitable, except I can't
find it now.  Can anyone locate this?

on where you want to put it in the docs.

where would you put it in 3.1.?


Hmm.  I was initially thinking of 3.1.2, but that subsection
(actually, the entire section) is really talking about
*macroscopic* style.  I mean, it refers back to the definition of
a (compound) music expression.

With that in mind, perhaps 2.3.1 is the best place: add 2-3
sentences and an articulation (or dynamic, or something) to the
first paragraph+example.


That said, this is really Trevor's area now.  Let's see what he
says.


Thanks for the prompt!  I think the best place is in
2.1.2 Simple notation, in the Durations (rhythms) section.
This is where the entry of a duration is first mentioned,
and it's immediately after introducing the ' and , marks.
Perhaps immediately after the example there and before
dotted notes are mentioned would be ideal.  I'd be happy to
receive a patch, Simon.

I'd really appreciate an appendix or something that gives Lily syntax
as BNF, or as a syntax diagram.   The syntax is very complex, and I've
been caught out a number of times by things not being as I expected
them to be from the NR --- not that the NR was wrong, but that the way
elements are combined wasn't explicit.
