I'm running into issues trying to understand the document numbering for MIL documents. Is there somewhere that the numbering convention is defined?

I'm trying to link MIL-P-23377 to MIL-PRF-23377 but cannot find any definitive documentation to link them other than the last 5 digits. What's the difference between the "P" and the "PRF"?
