Description Erik Arvidsson 2012-11-12 11:15:04 PST 
Right now the message is "HIERARCHY_REQUEST_ERR: DOM Exception 3".

The message should be the "Description" from http://dom.spec.whatwg.org/#error-names-table

Oh, I never envisioned the description to be used for this. Currently IDL defines the message field as user-agent defined.

OK.

I still think the message property of the exception object in WebKit should be:

  "The operation would yield an incorrect node tree"

instead of

  "HierarchyRequestError: DOM Exception 3"

With bug 101955 and my proposed change the web inspector will print:

  "HierarchyRequestError: The operation would yield an incorrect node tree"

instead of:

  "Error: HierarchyRequestError: DOM Exception 3"

Looks OK nowadays.
