Example / specification URLs are dead

There are references in the docs to XML specifications, property lists, etc, that are dead URLs. For example:

https://github.com/AdobeDocs/dynamic-media-developer-resources.en/blob/67e12fae514341137e4218ea950f34da0d9997f3/help/aem-is-ir-api/is-api/http-ref/image-serving-api-ref/c-http-protocol-reference/c-syntax-and-features/r-media-set-requests.md?plain=1#L119

Are these resources moved somewhere else? Can these URLs be updated?

Thanks!

Start with the referenced c-media-set-requests.md file and inspect its links to XML specifications and property lists. Verify which URLs are dead and whether replacement resources can be identified; done means the affected documentation links resolve to the intended resources.
