[jira] Created: (XALANJ-2409) LSSerializerImpl adds redundant
xmlns:xml namespace bindings.
LSSerializerImpl adds redundant xmlns:xml namespace bindings.
-------------------------------------------------------------
Key: XALANJ-2409
URL: https://issues.apache.org/jira/browse/XALANJ-2409
Project: XalanJ2
Issue Type: Improvement
Components: Serialization
Reporter: Chris Simmons
Priority: Minor
Appologies if I'm logging this against the wrong component. I'm using the LSSerializerImpl bundled with xerces 2.9.0 which I believe is actually drawn from the Xalan project nowadays.
We switched over when the xerces serializers were deprecated but found tha the xalan serializer insists on adding bindings for the xml namespace. I (and the xerces serializer) believe that this is not necessary - the xml namespace is built-in.
This resulted in our XML being littered with thousands of needless xmlns:xml=... attributes. We've worked around this by making sure we put one on the document root. I'd like to see these attributes not serialized.
I'll attach a test showing this behviour shortly. It shows that xerces didn't add them but xalan does.

---------------------------------------
This is worse than I originally thought. The xerces parser explicitly throws away any xmlns:xml bindings presumably since they're implicit.
So if you start with a document that has no xml:xmlns attributes but uses the xml namespace, load it using xerces then serialize it using xalan (making *no changes*) it comes out splattered with xmlns:xml prefix bindings. Our documents contain thousands of elements with xml:lang attributes on them.

-------------------------------------------------
We've just switched to Xalan 2.7.1 (from Xalan 2.7.0 with Xerces 2.7.1) and see the same effect.
