-- | Output the HTML without adding newlines or spaces within the markup.
--   This should be the most time and space efficient way to

-- | Outputs indented HTML, with indentation inside elements.
--   This can change the meaning of the HTML document, and

--   The implementation is inefficient, and you are normally
--   better off using 'showHtml' or 'renderHtml'.
