-| `http.host` | string | The value of the [HTTP host header](https://tools.ietf.org/html/rfc7230#section-5.4). When the header is empty or not present, this attribute should be the same. | `www.example.org` | `Conditionally Required` <condition> | Experimental |
-| [`http.server_name`](http.md) | string | The primary server name of the matched virtual host. [1] | `example.com` | `Conditionally Required` [2] | Experimental |
-| `http.status_code` | int | [HTTP response status code](https://tools.ietf.org/html/rfc7231#section-6). | `200` | `Conditionally Required` if and only if one was received/sent. | Experimental |
 | `faas.execution` | string | The execution id of the current function execution. | `af9d5aa4-a685-4c5f-a22b-444f80b3cc28` | `Recommended` | Experimental |

-**[1]:** http.url is usually not readily available on the server side but would have to be assembled in a cumbersome and sometimes lossy process from other information (see e.g. open-telemetry/opentelemetry-python/pull/148). It is thus preferred to supply the raw data that is available.

-**[3]:** This is not necessarily the same as `net.peer.ip`, which would identify the network-level peer, which may be a proxy.

-Allow to define additional requirements on the semantic convention.
-Currently, it supports `any_of` and `include`.

-#### Any Of
-
-`any_of` accepts a list of sequences. Each sequence contains a list of attribute ids that are required.
-`any_of` enforces that all attributes of at least one of the sequences are set.

-#### Include
-
-`include` accepts a semantic conventions `id`. It includes as part of this semantic convention all constraints
-and required attributes that are not already defined in the current semantic convention.
