Re: 2. Effect of normalisation step on the DOM/Infoset

/ Ian Hickson <ian@hixie.ch> was heard to say:
| | 4 Processing xml:id Attributes
| |
| | Each xml:id attribute is processed in the following way:
|
| It is unclear whether this processing is intended to change the DOM
| (or the infoset, for that matter) or not. If one has the following
| document:
|
|    <test xml:id=" test "/>
|
| ...what would be returned by:
|
|    document.documentElement.getAttributeNS('http://www.w3.org/XML/1998/namespace', 'id');
|
| Should it be " test " or "test"?
|
| I think it should be made clear that the processing mentioned in this
| section is merely internal to the xml:id processor and does not affect
| the infoset or the DOM. (This comment obviously doesn't apply to the
| "ID Assignment" phase, where you definitely do want the infoset and
| the DOM to be updated, but that's another matter.)

On the contrary, I think the purpose of attribute value normalization is
so that down-stream processes will see the normalized value.

I think the result of processing your example with an xml:id Processor
should be the same as the result of processing this document with a
standard parser:

<!DOCTYPE test [
<!ATTLIST test xml:id ID #IMPLIED>
]>
<test xml:id=" test "/>

                                        Be seeing you,
                                          norm
