Bug description

On the description page https://maven.apache.org/whatsnewinmaven4.html#new-packaging-type-bom

Therefore, the Maven team suggests that project BOMs should be generated as classified artifacts, using the <bomClassifier> element. This means that an imported BOM must not come from the same reactor as the current build but be available outside the project before the build.

Here is given a reference to bomClassifier, but there is no reference in the XSD file for Model Version 4.1.0 nor have I found an example how to use bomClassifier

Do I simply miss a thing here?

Contributor guide

Research direction
Review the Maven Model XSD for version 4.1.0 to confirm if `bomClassifier` is defined. Inspect the documentation page for the BOM packaging type and find an example of using `bomClassifier`. If missing, add the definition to the XSD and update the documentation or example accordingly.
