    <p>That's why I think the (namespace) principle / "grammar" should
      be discussed<br>
      instead of inventing the wheel from scratch for every shop<br>
      (and having endless discussions about differences between slightly
      different shops<br>
      instead of letting people express the details with an easy
      "grammar" / "subkeys").<br>

          similar to what you created on the skateboarding page:
