Where is the RSS code?

Hey everyone,

I’ve been tasked to use a client’s WordPress site to adhere to various RSS rules for podcasting platforms. In particular, Google has a set of requirements and recommendations that go beyond the standard setup for a default WordPress RSS. While I could theoretically code my own custom RSS feed, I’d rather simply update the existing codebase instead of having to manage them separately.

Thus, I’m reaching out to you to learn where, in WordPress’ code base, exists the RSS code? I’ve searched in functions.php to no avail, and after doing more searching, I’ve come up blank. Any help would be appreciated.

Thank you!
