Re: Query on DOM range methods

Yes, this is one of the 2 queries I wanted an answer i.e the expected behaviour when element node is a root container. But, I don't see this behaviour called out anywhere in any version of the specs.

The other query I had, are the constraints for range methods  specified in DOM2 still valid along with new behaviour specified in DOM4.

For ex:
setStartBefore in DOM2 :
    Sets the start position to be before a node
    Parameters
        refNode of type Node
        Range starts before refNode

    Exceptions
        RangeException
            INVALID_NODE_TYPE_ERR: Raised if the root container of refNode is not an Attr, Document, or DocumentFragment node or if refNode is a    Document, DocumentFragment, Attr, Entity, or Notation node.

        DOMException
            INVALID_STATE_ERR: Raised if detach() has already been invoked on this object.

setStartBefore in DOM4 :
    Let parent be node's parent.
    If parent is null, throw an "InvalidNodeTypeError" exception.
    Set the start of the context object to boundary point (parent, node's index).

I hope, DOM2 spec is not deprecated one, the behaviour is still valid.

Thanks,
Bhanu

Yes it could be.

var r = new Range()
var e = document.createElement("test")
var ec = e.appendChild(document.createElement("test"))
r.setStartBefore(ec)
alert(r.startContainer == e)

If you mean something else you'll have to be more clear.
