Docu Sect. 3.5.2

[Juergen Reuter]

The introduction for the Gregorian transcription template currently says:

"This example demonstrates how to do modern transcriptions of Gregorian 
music. Gregorian music has no measure, no stems; it uses only half and 
quarter notes, and two types of barlines, a short one indicating a rest, 
and a second one indicating a breath mark."

The template has been recently updated, such that the text is now somewhat 
outdated.  I would like to propose a slightly modified text, maybe 
something like:

"This example demonstrates how to do modern transcription of Gregorian
music. Gregorian music has no measure, no stems; it uses only half and 
quarter noteheads, and special marks, indicating rests of different 
length."

Greetings,
