I feel the following may be considered as significant:
1. Clarification that the rules outlined apply to PTE updates
caused by an explicit or an implicit memory access.
2. The text where the privileged spec stated "and the sequence is
interruptible." is updated to clarify that a trap may occur
between PTE update and the memory access that caused the PTE
3. The extension requires page tables to be located in cacheable
main memory PMA regions.
