Re: extra-offset instead of X/Y offset? (was Lowering a mark)

[Mats Bengtsson]

I recommend you to primarily use the padding and staff-padding 
properties to adjust the vertical position of objects. Then, LilyPond 
will automatically take the new position of the object
into account, for example when calculating the distance to the next 
stave. If you use extra-offset, the object will be moved
after all other typesetting decisions have been made, i.e. nothing else 
will move (which sometimes is an advantage, but often not).


Regarding the padding of dynamics, the DynamicLineSpanner
object is mentioned under "Commonly tweaked properties" in the section 
on Dynamics. However, only in connection to the staff-padding property, 
not the padding property.

Could you please propose more exactly how to modify the
documentation, based on your experience of where you searched
and didn't find it. See
