Parameters
This template accepts the following parameters:

 * - any extra CSS classes to be added.
 * - If set to "yes", "y", "true" or "1", adds the CSS class "selfref". This is used to denote self-references.

Errors
If no hatnote text is supplied, the template will output the following message:

If you see this error message, it is for one of four reasons:
 * 1) No parameters were specified (the template code was ). Please use   instead.
 * 2) Some parameters were specified, but the hatnote text wasn't included. For example, the template text  will produce this error. Please use (for example)   instead.
 * 3) The hatnote text was specified, but that text contains an equals sign ("="). The equals sign has a special meaning in template code, and because of this it cannot be used in template parameters that do not specify a parameter name. For example, the template code  will produce this error. To work around this, you can specify the parameter name explicitly by using   before the hatnote text, like this:.
 * 4) You tried to access directly by using  . Use of #invoke in this way has been disabled for performance reasons. Please use   instead.
