After some time for reflection, I think we'll stick with the
non-standard feature.  If users want to, they can use TclDOM
in such a manner that it is standard (ie. create node using
factory method, then insert).

My plan for TclDOM is to make a 'theta' release like I did
for TclXML.  That work will involve bringing the C and Tcl
implementations into sync, as well as perhaps adding support
for tDOM-style features, like more OO style node commands.
Of course, we'll throw in DOM Level 2 and 3 support for 
good measure ;-)

Now I just have to find the time...

Cheers,
