You are right, I was aware of that, but I copied one of my older attempts
(which was wrong). :)

Yes, that would be possible. However, in that case, it's only _one_ product
with different releases.

If I want to use different productnumbers and productnames, this would no
longer be possible because the "cohersion" would be missing.

For example, to express different products inside the same <meta>, I would have
to use <phrase> like this:

  <meta name="products">
     <phrase>
        <productnumber>10SP1,10SP2,10SP3</productnumber>
        <productname>The ABCD long product name</productname>
        <abbrev>ABCD</abbrev>
     </phrase>
       <!-- ... second product ... -->
     <phrase>
     </phrase>
  </meta>

It's possible, but not sure if this is something I would use. ;-) Probably also
a matter of taste.

Ah, I see. Thanks for the clarification.

Yes, that would be an option.


Thank you for the ideas.
