How to remove a property using the Content Definitions API

Hi,

As the title suggests. How do I remove a property from a content type using the Content Definitions API?

Please note: the question applies to content types that have content items AND where the property I wish to remove has a value.

Have tried:

1. Semantic versioning on|off
2. Providing different versions in the payload.
3. Using the query parameters "allowedUpgrades=major" and "allowedDowngrades=major"

Thanks in advance.
