| $params | array | string | The parameters where key is the attribute name and the value the attribute value. When string will simply prepend with the prepend-string (by default `' '`) unless $params is falsey in which case an empty string is returned. This alternative syntax is used by the method internally. |
| $method | string | When used as a context handler, the method the handler was called for I.e. `'wrap'`. Currently not used by the method. |
| $options | array | Available options are: - `'escape'` _boolean_: Indicates whether the output should be HTML-escaped. Defaults to `true`. - `'prepend'` _string_: String to prepend to each attribute pair. and the final result. Defaults to `' '`. - `'append'` _string_: String to append to result. Defaults to `''`. |
