[whatwg] <!doctypehtml> triggers standards mode

Just an observation. I discovered that "<!doctypehtml>" triggers standards 
mode in Mozilla, IE6 and Opera. SGML required whitespace between the 
tokens[1] but browsers seem to recognize the tokens even without 
whitespace[2]. For instance,

<!doctypehtmlpublic"-//W3C//DTD HTML 

triggers standards mode, while

<!doctypehtmlpublic"-//W3C//DTD HTML 4.01 Transitional//EN">

triggers quirks mode.
