Therefore, step 8 should read: "8. Return <i>node</i>." This is critical, because the value returned by pre-insert algoritm is passed on to and returned by the Node.appendChild(node) and Node.insertBefore(node, child) method. If implemented as is, Node.appendChild(node) will ALWAYS return null, whereas it must return the inserted node. 65717 1 Ms2ger 2012-03-18 18:45:26 +0000 Good catch, thanks. https://bitbucket.org/ms2ger/dom-core/changeset/1f02e4a8b80c https://dvcs.w3.org/hg/domcore/rev/1f02e4a8b80c
