  You completely confuse *bindings* and *implementation*.
the binding is the software contract, the implementation is the way it is
implemented.
  There is NO reference implementations at W3C
  DOM only has normative bindings for Java and Javascript, the IDL is also 
normative
   http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113/idl-definitions.html

 The C bindings get normative through the normative IDL to C translation
defined at the OMG.

  Use CORBA, you do not need a C ABI for DOM. And if you try to get
one it won't work well. The DOM implementation is tied to the browser
internal representation of the data, you cannot impose an ABI for this.
But you can try to speak to them though DOM + CORBA.
