What You Are Seeing?

When trying to pack a package with an empty checksum element, the CPMR0001 rule get triggered. This does not happen for packages going through the validator.

What is Expected?

That packages with an empty checksum element do not fail CPMR0001, to be consistent with the validator behavior. https://community.chocolatey.org/packages/libreoffice-fresh

1. Get the source libreoffice-fresh at https://github.com/chocolatey-community/chocolatey-packages/tree/master/automatic/libreoffice-streams
2. Run choco pack in the directory
3. See that pack fails with CPMR0001

[AdmiringWorm]

It is intentional that the rule is stricter than the implementation in package validator. In this, we are taking what the rule description is specified as, instead of doing a 1-to-1 like of the implementation in package validator. If it had been the other way around, that this extension wouldn't have flagged the empty Copyright element, but the package validator had flagged it, this would have been a bug.
