Hi again,
It appears that images are not possible, or I made a mistake, so I will
post the text variant as follow up.
A dependency example with *maven 4.0.0-alpha12*
<dependencies>
<dependency>

A dependency example with *Maven 3.9.6*
<dependencies>
<dependency>

Or like the dependencyManagement element with *Maven 4.0.0-alpha12*
<dependencyManagement>
<dependencies>
<dependency>

line 16 from org.example:mng-7344-bom-a:1-SNAPSHOT-->
</dependency>
<dependency>

</dependency>
</dependencies>
</dependencyManagement>
The dependencyManagement element *Maven 3.9.6*
<dependencyManagement>
