i have a piece of Javascript code which walks the DOM tree doing various transformations. sometimes i need to alter the value (ie the children) of an attribute node, but Firefox seems to disallow this.

Reproducible: Always

Steps to Reproduce:
1. make a text node
2. try to add it to an attribute node as a child
3. error results
Actual Results:  
call failed with error --

uncaught exception: [Exception... "Component returned failure code: 0x80004001 (NS_ERROR_NOT_IMPLEMENTED)" nsresult: "0x80004001 (NS_ERROR_NOT_IMPLEMENTED)" location: "JS frame :: file:///Users/jason/janx/web/janx/tree_walker.js :: anonymous :: line 287" data: no]


Expected Results:  
i expected the call to succeed as it does on other DOM implementations (eg WebKit) and as the specification describes. attributes may have multiple child nodes -- eg if there is an entity reference inside the text or something -- and the child list should be read only.

Chrome passes this test, Opera 10.10 throws a HIERARCHY_REQUEST_ERR. IE doesn't throw, but doesn't actually append a child to the Attr node.

I'm not convinced that DOM3CORE actually defines what should happen here.

Invalid per DOM4.
