allowed-page-breaks-001a (paged): allowed page breaks between blocks
Unforced breaking in the vertical margin between sibling block boxes is allowed only if the 'page-break-after' and 'page-break-before' properties of all the elements generating boxes that meet at this margin are 'auto' and the common ancestors of all the elements do not have a 'page-break-inside' value of 'avoid'.

Breaking between line boxes is allowed only if the number of line boxes between the break and the start of the enclosing block box is the value of 'orphans' or more, and the number of line boxes between the break and the end of the box is the value of 'widows' or more and the value of the 'page-break-inside' property is 'auto'.
allowed-page-breaks-003 (paged): allowed page break - dropping page-break-* restrictions

allowed-page-breaks-004 (paged): allowed page break - dropping widows and orphans restrictions
If the standard restrictions do not provide enough break points to keep content from overflowing the page boxes after dropping the restrictions imposed by 'avoid' on the 'page-break-*' properties then the restrictions due to 'windows' and 'orphans' are dropped as well.
