> Just noticed that Maven 4 has a new namespace URL. The old namespace was
>  
> [http://maven.apache.org/POM/4.0.0]
>  
> The new one is
>  
> [http://maven.apache.org/POM/4.1.0]

> Putting version numbers in namespaces is a known XML antipattern because it makes it extremely difficult and inconvenient to write tools that process both, even when they are much the same. XSLT, DOM, XQuery, JDOM, etc. — really any XML aware tool — is going to have problems with this.
> Model version 4.1.0 is not a new and different schema that completely breaks with the past. Most old elements from 4.0.0 are still present and still mean exactly the same thing: groupId, artifactId, name, dependency, and most others. There are new elements but that doesn't imply a new namespace. Adding a new namespace is asserting that all the elements are different.
> IMHO Maven 4 should not change the namespace URL.
