UML24 — Deep history for orthogonal states

"A region may have at most one deep history vertex." (pg 564)
"A composite state may have at most one deep history vertex." (pg 557)

This implies that only one region of a composite state may have a deep history vertex. There is no formal constraint to the effect. Please clarify.

"deepHistory represents the most recent active configuration of the composite state that directly contains this pseudostate" (pg 557)
This implies that all regions of a orthogonal composite state are returned to the the most recent active configuration of the composite state but...at the bottom of page 570 it asserts the other regions are entered "by default" which has a different semantic. Please clarify.

The second quoted sentence is no longer there, but there is still some text that implies that history vertices
are State based rather than Region based. These should be fixed.
Fix all places where it is implied that history vertices belong to States rather than Regions.
