XML namespace
Maven POM 4.0.0
The default namespace on pom.xml, covering Maven project coordinates, dependencies, build plugins, profiles, and repositories.
xmlns="http://maven.apache.org/POM/4.0.0"Maven project files declare this as their default namespace on <project>. The 4.0.0 segment is the model version, not the Maven executable version, so modern Maven releases still emit the same URI.
The schema-location pair commonly points to maven-4.0.0.xsd, but the namespace URI is the vocabulary identity. Maven builds an effective model with inheritance and defaults beyond what XSD validation can express.
