-Package html implements an HTML5-compliant tokenizer and parser.
-
-Tokenization is done by creating a Tokenizer for an io.Reader r. It is the
-caller's responsibility to ensure that r provides UTF-8 encoded HTML.
-
-	z := html.NewTokenizer(r)
-
-Given a Tokenizer z, the HTML is tokenized by repeatedly calling z.Next(),
-which parses the next token and returns its type, or an error:
-
-	for {
-		tt := z.Next()
-		if tt == html.ErrorToken {
-			// ...
-			return ...
-		}
-		// Process the current token.
-	}
-
-There are two APIs for retrieving the current token. The high-level API is to
-call Token; the low-level API is to call Text or TagName / TagAttr. Both APIs
-allow optionally calling Raw after Next but before Token, Text, TagName, or
-TagAttr. In EBNF notation, the valid call sequence per token is:
-
-	Next {Raw} [ Token | Text | TagName {TagAttr} ]
-
-Token returns an independent data structure that completely describes a token.
-Entities (such as "&lt;") are unescaped, tag names and attribute keys are
-lower-cased, and attributes are collected into a []Attribute. For example:
-
-	for {
-		if z.Next() == html.ErrorToken {
-			// Returning io.EOF indicates success.
-			return z.Err()
-		}
-		emitToken(z.Token())
-	}
-
-The low-level API performs fewer allocations and copies, but the contents of
-the []byte values returned by Text, TagName and TagAttr may change on the next
-call to Next. For example, to extract an HTML page's anchor text:
-
-	depth := 0
-	for {
-		tt := z.Next()
-		switch tt {
-		case html.ErrorToken:
-			return z.Err()
-		case html.TextToken:
-			if depth > 0 {
-				// emitBytes should copy the []byte it receives,
-				// if it doesn't process it immediately.
-				emitBytes(z.Text())
-			}
-		case html.StartTagToken, html.EndTagToken:
-			tn, _ := z.TagName()
-			if len(tn) == 1 && tn[0] == 'a' {
-				if tt == html.StartTagToken {
-					depth++
-				} else {
-					depth--
-				}
-			}
-		}
-	}
-
-Parsing is done by calling Parse with an io.Reader, which returns the root of
-the parse tree (the document element) as a *Node. It is the caller's
-responsibility to ensure that the Reader provides UTF-8 encoded HTML. For
-example, to process each anchor node in depth-first order:
-
-	doc, err := html.Parse(r)
-	if err != nil {
-		// ...
-	}
-	var f func(*html.Node)
-	f = func(n *html.Node) {
-		if n.Type == html.ElementNode && n.Data == "a" {
-			// Do something with n...
-		}
-		for c := n.FirstChild; c != nil; c = c.NextSibling {
-			f(c)
-		}
-	}
-	f(doc)

-// 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>".
