 This track is for tags with complex validation logic and ratcheting. These tags begin at the **Alpha** stability level.
 
+This track is for tags that are always used in combination with other tags or that have complex ratcheting logic. All cross-field validations belong in this category. Additionally, for most of these tags, there is no clear alternative in the OpenAPI schema.
