HTTP/2 defines the SETTINGS frame to contain a single 32-bit value per setting. While this is sufficient to convey everything used in the core HTTP/2 specification, some protocols will require more complex values, such as arrays of code-points or strings. For such protocols, this extension defines a parallel to the SETTINGS frame, EXTENDED_SETTINGS, where the value of a setting is not a 32-bit value, but a variable-length opaque data blob whose interpretation is subject entirely to the definition of the protocol using it.
