Should I check for prohibited strings?

[NorioKobota]

SPDX v2.2 or later, Some fields have restricted input values.
Do I need to check these restricted strings in these fields in another way?
I would appreciate it if you could tell me how you all are doing. (don't care, just ignoring etc.)

ex.
Package Supplier is defined as follows, but currently, if an arbitrary string such as "Tool: " is written, an error is not detected during conversion with this tool.
https://spdx.github.io/spdx-spec/v2.3/package-information/#75-package-supplier-field

Single line of text with one of the following:
NOASSERTION
Person: person name and optional (<email>)
Organization: organization name and optional (<email>)
Package supplier is not allowed to Currently

Best regards.
