Where Would this go in BCD?

I notice that Subresource Integrity has the standard ‘help us convert’ message. I need to reference this soon and want it show the up-to-date format. Where do I store it in the compatibility db? It doesn’t fit into any of the existing folder/categories (api, browsers, css, etc.).

Well from the topic it seems to me that it belongs either in http/headers (but it is not a header) or api section.

but I am still starting with the project. so any pointers about the design rationals would be helpful. but I might get to this when I finish reading all docs.
