HTTP request method.
<p>
HTTP request method value SHOULD be "known" to the instrumentation.
By default, this convention defines "known" methods as the ones listed in <a
href="https://www.rfc-editor.org/rfc/rfc9110.html#name-methods">RFC9110</a>, the PATCH method
defined in <a href="https://www.rfc-editor.org/rfc/rfc5789.html">RFC5789</a> and the QUERY method
defined in <a
href="https://datatracker.ietf.org/doc/draft-ietf-httpbis-safe-method-w-body/?include_text=1">httpbis-safe-method-w-body</a>.
<p>
If the HTTP request method is not known to instrumentation, it MUST set the @code
http.request.method @endcode attribute to @code _OTHER @endcode. <p> If the HTTP instrumentation
could end up converting valid HTTP request methods to @code _OTHER @endcode, then it MUST provide
a way to override the list of known HTTP methods. If this override is done via environment
variable, then the environment variable MUST be named OTEL_INSTRUMENTATION_HTTP_KNOWN_METHODS and
support a comma-separated list of case-sensitive known HTTP methods. <p>
If this override is done via declarative configuration, then the list MUST be configurable via the
@code known_methods @endcode property (an array of case-sensitive strings with minimum items 0)
under @code .instrumentation/development.general.http.client @endcode and/or
@code .instrumentation/development.general.http.server @endcode.
<p>
In either case, this list MUST be a full override of the default known methods,
it is not a list of known methods in addition to the defaults.
<p>
HTTP method names are case-sensitive and @code http.request.method @endcode attribute value MUST
match a known HTTP method name exactly. Instrumentations for specific web frameworks that consider
HTTP methods to be case insensitive, SHOULD populate a canonical equivalent. Tracing
instrumentations that do so, MUST also set @code http.request.method_original @endcode to the
original value.

A static path segment is a part of the route template with a fixed, low-cardinality value. This

A dynamic path segment is a placeholder for a value that can have high cardinality and is not
constrained to a predefined list like static path segments. <p> Instrumentations SHOULD use
routing information provided by the corresponding web framework. They SHOULD pick the most precise
source of routing information and MAY support custom route formatting. Instrumentations SHOULD
document the format and the API used to obtain the route string.
