Use when creating a new (i.e. NON-EXISTANT) HTML document.

Use when parsing an existing COMPLETE HTML document, but NOT a fragment.
Use Nokogiri::HTML::DocumentFragment.parse when parsing a fragment
string (i.e., INCOMPLETE DOCUMENT).

As stated above, these do two different things, although you may end up
