-// [Protovalidate](https://protovalidate.com/) is the semantic validation library for Protobuf.
-// It provides standard annotations to validate common rules on messages and fields, as well as the ability to use [CEL](https://cel.dev) to write custom rules.
-// It's the next generation of [protoc-gen-validate](https://github.com/bufbuild/protoc-gen-validate).
-//
-// This package provides the options, messages, and enums that power Protovalidate.
-// Apply its options to messages, fields, and oneofs in your Protobuf schemas to add validation rules:
-//
-// ```proto
-// message User {
-//   string id = 1 [(buf.validate.field).string.uuid = true];
-//   string first_name = 2 [(buf.validate.field).string.max_len = 64];
-//   string last_name = 3 [(buf.validate.field).string.max_len = 64];
-//
-//   option (buf.validate.message).cel = {
-//     id: "first_name_requires_last_name"
-//     message: "last_name must be present if first_name is present"
-//     expression: "!has(this.first_name) || has(this.last_name)"
-//   };
-// }
-// ```
-//
-// These rules are enforced at runtime by language-specific libraries.
-// See the [developer quickstart](https://protovalidate.com/quickstart/) to get started, or go directly to the runtime library for your language:
-// [Go](https://github.com/bufbuild/protovalidate-go),
-// [JavaScript/TypeScript](https://github.com/bufbuild/protovalidate-es),
