 ### Stable Specifications
 When draft specifications are used by third parties, they become **stable** specifications. Changes to stable specifications should be restricted to errata and clarifications. Stable specifications are contracts between editors, implementers, and end-users.

-When stable specifications are replaced by newer draft specifications, they become **legacy** specifications. Legacy specifications should not be changed except to indicate their replacements, if any. Legacy specifications are contracts between editors, implementers and end-users.
