Widows/orphans

[MRoth1910]

• Sections (chapters) cannot begin at the bottom of a page
• date (movable or fixed), feast title, rank cannot be split. Ideally, "In I (II) Vesperis" and simiilar are not split either.
• "Canticum Simeonis", Scriptural reference, and chant cannot be split.
• "Capitulum" and Scriptural reference cannot be split from capitulum itself.
• "Oratio" and collect cannot split.
• "Oremus" cannot in the few places where it's printed. Nor can "Amen" (ideally).
• Rubrics typed separately from score can't split.
• Antiphons can split, although this might lead to unfortunate break with only EUOUAE or TP Alleluia on next page.
• Verse and response probably can split, but we should see if they fit on one line as well.
