Namespace settings-1.0.0.xsd correct?

Currently the namespace chosen in the settings XSD is the same as the
one chosen in the POM XSD. This causes conflicts e.g. when using XML
catalogs to resolve the XSD files (e.g. when using the WTP/XML Catalog
support in Eclipse):

POM XSD :

http://maven.apache.org/maven-v4_0_0.xsd

POM example:

<project
xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
...
</project>

Settings XSD :

http://maven.apache.org/xsd/settings-1.0.0.xsd

Settings example :

<settings
xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
...
</settings>

Having one namespace pointing to two different XSD files, depending on
whether you're editing a POM or a settings file isn't a good idea.

Question : can't the namespace of the settings XSD be changed or would
this have too much of an impact on M2 (e.g. when M2 currently uses a
namespace aware parser to parse the XML files)?
