WOComponentContent allows you to write nested components as HTML container elements: Elements that can include text and other elements between their opening and closing tags. Using WOComponentContent you can, for example, write a component that defines the header and footer for all of your application's pages.
The WOComponentContent dynamic element doesn't have any attributes. It's simply a marker that specifies where the contents wrapped by the component's <WEBOBJECT> tag should go.
You can only have one WOComponentContent element in a given component.
