Include Content Only Once

Use singleton to wrap contents (tag, text, HTML, or lists) that should be included in the generated document only once, yet may appear in the document-generating code more than once. Only the first appearance of the content (in document order) will be used. Useful for custom components that have JavaScript files or stylesheets.
