At the conclusion of the Final Comment Period, the Architecture Committee today decided to accept the policy as summarized in my last mail:
- Use `Accept` headers for format negotiation. - Strongly encourage users to explicitly request a specific format version, and update the default format promptly. We will now document and implement this policy. The first use of content negotiation will be an upcoming change in Parsoid's HTML format.
