           HTTP request method SHOULD be one of the methods defined in [RFC9110](https://www.rfc-editor.org/rfc/rfc9110.html#name-methods)
           or the PATCH method defined in [RFC5789](https://www.rfc-editor.org/rfc/rfc5789.html).
           Instrumentation MAY additionally support the closed set of custom HTTP methods defined in
           [HTTP method registry](https://www.iana.org/assignments/http-methods/http-methods.xhtml) or a private registry.
           Instrumentation MUST set the `http.method` attribute to `OTHER` if the HTTP request method is not known to the instrumentation.
+
+          HTTP method names are case-sensitive and `http.method` attribute value MUST match a standard (or documented elsewhere) HTTP method name exactly.
