      public @interface PublishEvent

  Marks an event handler method to be published as an event to be called in JavaScript through the `t5/core/ajax` function when the `options` parameter has an `element` attribute.

  The logic for obtaining the URL is actually located implemented in the `t5/core/dom.getEventUrl(eventName, element)` function.

  The event information is stored in JSON format inside the "data-component-events" attribute.

  When used in a component method, the component must render at least one element, and that's what gets the "data-component-events" attribute above. If it doesn't, an exception will be thrown.

  When used in a page method, the page must render an <body> element. If it doesn't, an exception will be thrown.
