Re: [MMUSIC] 4566bis-36: Minor editorial comments regarding line descriptions in section 5

[Paul Kyzivat <[e-mail]>]

Christer,

It seems to me that these are all minor editorial things. Since the 
document has already had its IESG review I am reluctant to make such 
optional changes. If I were to start I can imagine some further back and 
forth on the details of the wording. But I can do these if Adam wants them.

	Thanks,
	Paul
