With respect to the node Interface, it defines node.attributes as a read-only named node map.
This implies any attempt to modify the map e.g. using setNamedItem() should raise exception.
In ihdSim no exception is raised , in fact the attributes are modified.
Is this a bug
Thanks

(possible)Bug in DOMCORE API :::: node.attributes

P.S. What about the read-only members firstChild and lastChild.
Those seem to be easily replaceable/removable....
