As happens in economics, different lawyers can have different interpretations. Our practices were consulted with the SPDX guys but other projects have different practices. While the sound practice, especially when you don't own the code, is to add the SPDX tag in addition to the license text, the linux developers are encouraging replacing it altogether with the SPDX tag. In their case they keep a reference to the complete license text elsewhere and they have some repository log where the copyright owner did the change. For contrib code we just follow upstream. In no case can anyone other than the copyright owner clarify, or otherwise change, a license. Pedro.
