[Bug]: Validator does not raise error on missing ``DynamicTableRegion.table/description`` attributes

[oruebel]

What happened?

In https://github.com/NeurodataWithoutBorders/pynwb/issues/1468#issuecomment-1121507931 @CodyCBakerPhD shows a case where the required attributes table and description are being omitted/removed from a DynamicTableRegion. This (not surprisingly) causes the file to fail on read, however, validation still passes. This seems to indicate that there is some sort of bug or error with the validator, in that it either fails to check for (some) attributes or assumes that attributes are optional when they should be treated as required.
