HRS §560:2-704
When a minor mistake in exercising a power of appointment is okay
This section says that if a person with a power of appointment tries to use it, they don't have to follow every exact rule in the original document. As long as they know they are using the power and intend to, and their attempt doesn't go against the main reason the rule was made, it counts.

The statute, as written — Power of appointment; meaning of specific reference requirement
A powerholder's substantial compliance with a formal requirement of appointment imposed in a governing instrument by the donor, including a requirement that the instrument exercising the power of appointment make reference or specific reference to the power shall be sufficient if: (1) The powerholder knows of and intends to exercise the power; and (2) The powerholder's manner of attempted exercise does not impair a material purpose of the donor in imposing the requirement.
