RTFSpec. However, since it says there that “*no* whitespace normalization
is performed” with “textContent”, you do not have to concern yourself with
that in “textContent” emulation.
However, ISTM that at least Chromium “Version 32.0.1700.123 Debian
jessie/sid (248368)” does not implement “textContent” as specified: “the
returned string does not (read: MUST NOT) contain the white spaces in
element content (read: “element content whitespace” as per XML), but it does
there. With
var div = document.createElement("div");
div.appendChild(document.createTextNode(" "));
var span = document.createElement("span");
span.appendChild(document.createTextNode(" "));
div.appendChild(span);
“div.textContent” yields four spaces there, but IIUC should yield only two
because the whitespace preceding the “span” element would be “element
content whitespace” per XML.
<http://www.w3.org/TR/2004/REC-xml-infoset-20040204/#infoitem.character>
The reason for that may be that the first child object implements the Text
interface of DOM Level 3 Core only incompletely: it implements the
splitText() method introduced in Level 1 Core, and the “wholeText” attribute
and replaceWholeText() method introduced in Level 3 Core; but it does not
implement the “isElementContentWhitespace” attribute also introduced in the
latter Specification.

Yes.
