-// Render renders the parse tree n to the given writer.
-//
-// Rendering is done on a 'best effort' basis: calling Parse on the output of
-// Render will always result in something similar to the original tree, but it
-// is not necessarily an exact clone unless the original tree was 'well-formed'.
-// 'Well-formed' is not easily specified; the HTML5 specification is
-// complicated.
-//
-// Calling Parse on arbitrary input typically results in a 'well-formed' parse
-// tree. However, it is possible for Parse to yield a 'badly-formed' parse tree.
-// For example, in a 'well-formed' parse tree, no <a> element is a child of
-// another <a> element: parsing "<a><a>" results in two sibling elements.
-// Similarly, in a 'well-formed' parse tree, no <a> element is a child of a
-// <table> element: parsing "<p><table><a>" results in a <p> with two sibling
-// children; the <a> is reparented to the <table>'s parent. However, calling
-// Parse on "<a><table><a>" does not return an error, but the result has an <a>
-// element with an <a> child, and is therefore not 'well-formed'.
-//
-// Programmatically constructed trees are typically also 'well-formed', but it
-// is possible to construct a tree that looks innocuous but, when rendered and
-// re-parsed, results in a different tree. A simple example is that a solitary
-// text node would become a tree containing <html>, <head> and <body> elements.
-// Another example is that the programmatic equivalent of "a<head>b</head>c"
-// becomes "<html><head><head/><body>abc</body></html>".
