Strictly speaking the `http://maven.apache.org/POM/4.0.0` is an identifier although in a form of URI. The referenced `https://maven.apache.org/xsd/maven-4.0.0.xsd` really declares **http://** URI as its `targetNamespace`: ``` <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; elementFormDefault="qualified" xmlns="http://maven.apache.org/POM/4.0.0"; targetNamespace="http://maven.apache.org/POM/4.0.0";> ``` so I'd say it's a lucky coincidence that a POM that uses `https://` namespace URI actually validates. Maybe some later authoritative statement from W3C changed that, [but originally](https://www.w3.org/TR/2009/REC-xml-names-20091208/#ns-decl) > The namespace name, to serve its intended purpose, SHOULD have the characteristics of uniqueness and persistence. It is not a goal that it be directly usable for retrieval of a schema (if any exists) -- This is an automated message from the Apache Git Service.
