 `<name>` is the namespace of the repository, and `<int>` is an integer specifying the number of tags requested.
 The response to such a request MAY return fewer than `<int>` results, but only when the total number of tags attached to the repository is less than `<int>`.
 Otherwise, the response MUST include `<int>` results.
+A `Link` header MAY be included in the response when additional tags are available.
+If included, the `Link` header MUST be set according to [RFC5988](https://www.rfc-editor.org/rfc/rfc5988.html) with the Relation Type `rel="next"`.
 When `n` is zero, this endpoint MUST return an empty list, and MUST NOT include a `Link` header.
 Without the `last` query parameter (described next), the list returned will start at the beginning of the list and include `<int>` results.
 As above, the tags MUST be in lexical order.

 When using the `last` query parameter, the `n` parameter is OPTIONAL.
 
+The registry SHOULD support at least `n=1000` tags in a single response.
+The client SHOULD avoid requesting more than `n=1000` tags in a single request.
+If the registry is unable to return all tags requested by the client, the registry MUST return a `413 Content Too Large` with `TAG_LIMIT_EXCEEDED` error <sup>[code-15](#error-codes)</sup> and include the header `OCI-Tag-Limit: <limit>`, where `<limit>` is the maximum tags per request supported by the registry.
