btw, I have tested now

http://127.0.0.1:8080/yanel/test/use-cases/namespaces.xml

on Mac OS X with Java

java version "1.5.0_19"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_19-b02-304)
Java HotSpot(TM) Client VM (build 1.5.0_19-137, mixed mode, sharing)

and it works, whereas it generates the following code:

<?xml version="1.0"?>
<yanel:root xmlns:yanel="http://www.wyona.org/yanel/1.0" xmlns:i18n="http://www.wyona.org/yanel/i18n/1.0" xmlns="http://www.w3.org/1999/xhtml" xmlns:xhtml="http://www.w3.org/1999/xhtml"><foo:hugo xmlns:foo="http://foo.bar" foo:dummy="susi"/>
<yanel:hello>world</yanel:hello>
</yanel:root>

and the log says:

23146 2009-06-26 00:09:00,527 [http-8080-Processor25] WARN  org.wyona.yanel.core.serialization.XMLSerializer.startElement():61  - DEBUG: Attribute     : xmlns:yanel, http://www.wyona.org/yanel/1.0

whereas I guess the i18n namespace comes from the 

I18n transformer inside

src/impl/java/org/wyona/yanel/impl/resources/BasicXMLResource.java

whereas it is not clear to me where the xhtml namespace comes from.
