The `requirements` section is limited to the attributes defined in this specification. Arbitrary key/value pairs are not allowed in the `requirements` section, and must instead be placed in the [`hints`](#-hints-section) section.

 The `hints` section is optional and may contain any number of attributes (key/value pairs) that provide hints to the execution engine. A hint provides additional context that the execution engine can use to optimize the execution of the task. The execution engine may also ignore any hint for any reason. A task execution never fails due to the inability of the execution engine to recognize or satisfy a hint.
