breaks broken

[sydb]

The att.breaking elements are:

• <cb> = column begin
• <gb> = gathering begin
• <lb> = line begin
• <pb> = page begin
• <milestone unit="somethingElse"> = boundary between somethings else

We allow:

schema	cb	gb	lb	pb	milestone
level 1		gb		pb
level 2		gb		pb
level 3	cb	gb	lb	pb
level 4		gb	lb	pb

Surely this can’t be correct. I’m guessing we want <cb> included at level 4, and <gb> included either in none or only at level 4.

Agree that cb needs to be in Level 4. As for gb, we haven't discussed that element anywhere, and my sense is that it's so specialized that we'd consider that to be Level 5 encoding (and thus we don't need to add it to anything).

agree -- <cb> and <lb> in levels 3, 4, <gb> removed completely

Fixed at 10f6eb2. We now allow:

schema	cb	gb	lb	pb	milestone
level 1				pb
level 2				pb
level 3	cb		lb	pb
level 4	cb		lb	pb
