/ Ian Hickson <ian@hixie.ch> was heard to say:
| |   2. ID assignment is performed.
|
| It should be stated explicitly that the value used for ID assignment
| is the normalised value obtained in the previous step.

Agreed. Done.

| Also, should the following:
|
|    xml:id=""
|
| ...be special-cased in the spec? At the moment a strict reading of the
| spec leads me to believe that such an attribute would make the element
| have an ID consisting of the empty string, which would thus be found
| by using, e.g.:
|
|    document.getElementById('')
|
| I would assume that much software has been written with the assumption
| that the empty string implies the lack of an ID. I would recommend
| changing step 2 of the processing section to read:
|
|    2. If this normalised value is not the empty string, ID assignment
|       is performed using the normalised attribute as the ID.
|
| This would take care of both these comments.

I'm inclined to agree.

                                        Be seeing you,
                                          norm
