Source notes citing this source

• RFC 8622 moved away from CS1 for lower-effort traffic because domains that treat CS1 as an RFC 2474 Class Selector can forward it with higher precedence than best-effort traffic (priority inversion). in context
• RFC 8622 updates RFC 4594 so that the Low-Priority Data class uses the LE codepoint 000001 (decimal 1) in place of CS1. in context
