Hi Vinayak,
I think you might be attaching over-much importance to the serialized form
of the document.
Nowadays--where everything XML'ish tends to get cast in terms of the XML
Information Set--I think the DOM spec writers don't think of the DOM as
conveying information about particular serialized forms, but rather they
think in terms of modeling an abstract collection of information--an XML
serialization of which is another alternative. Looked at in this way, the
original child2 element doesn't inherit anything from its parent: it has
its own namespace and namespace prefix property which the DOM models.
When you rename the child1 node in this way, abstractly what you're doing
it changing its namespace infoset property.
The DOM3 serialization API's are meant to provide as lossless a bridge as
possible between the DOM rendering of the infoset and its serialized form.
So it makes all the sense in the world not to change anything about the
child2 node, while simultaneously avoiding declaring redundant namespace
prefixes everywhere.
Hope that makes some sense. :)
Cheers,
Neil

I have a doubt regarding section B.1.2: in the dom 3 core spec and how the
new normalization routines will be implemented.
In the example :
<root>
<ns:child1 xmlns:ns="http://www.example.org/ns1";>
<ns:child2/>
</ns:child1>
</root>
here child2 intends to use the parent's interpretation of namespace ns ("
http://www.example.org/ns1";). THEN,
Using the method Node.renameNode, the namespace URI of the element child1
is renamed from "http://www.example.org/ns1"; to "http://www.example.org/ns2
".
Here is where the normalization is supposed to happen and the result, as
per the standards, is supposed to look like :
<root>
<ns:child1 xmlns:ns="http://www.example.org/ns2";>
<ns:child2 xmlns:ns="http://www.example.org/ns1"/>
</ns:child1>
</root>
I am not debating the standards. But logically, doesnt this look incorrect
? I mean, child2 is not specifying the value for the namespace and intends
to use the parent's namespace decl. So, if we rename the parent's namespace
ns, child should automatically inherit that same name. Logically, I would
expect the normalization routine to change nothing in this scenario and let
the output be :
<root>
<ns:child1 xmlns:ns="http://www.example.org/ns2";>
<ns:child2/>
</ns:child1>
</root>
Any comments ? bricks ?
