Web DOM Core: createElement convenience method (fwd)

Included below is feedback received on the WHATWG list for a proposed 
extension to createElement(). Since this applies to all of DOM Core, I 
haven't added it to HTML5, but I pass it on in case it is something that 
would apply to Web DOM Core.

FWIW, personally what I would find quite convenient too is an overloaded 
version of appendChild() that took a string, and automatically called 
document.createTextNode() on that string.

Cheers,

Hello again!

I was putting together a page of exercices for my students. It's in Swedish and
mirrored at http://gunther.ne.keryx.se/datagrund-ovningar/

This page must work when delivered from the file system so I can't use my
beloved PHP. However, I missed one feature like crazy. Consider this:

var link_to_add  = document.createElement("a");
var link_text    = document.createTextNode(the_text.nodeValue);
link_to_add.appendChild(link_text);

If PHP:s convenience additions to the W3C DOM were made standard (and
implemented in browsers) it could have been:

var link_to_add  = document.createElement("a",the_text.nodeValue);

What I propose is this second text-parameter to the createElement method (or a
third for createElementNS).

See http://se.php.net/manual/en/function.dom-domdocument-createelement.php
http://se.php.net/manual/en/function.dom-domdocument-createelementns.php

Has the standardization of this functionality ever been discussed? If so, can
someone point me to that discussion?

P.S In PHP I can also get the text between start- and end-tags of an element
with

element.nodeValue

instead of

element.firstChild.nodeValue

Even if I've yet to see any bad repercussions from this convenient shortcut, I
could imagine it is a bit more shaky...
