Dear George (and anybody who red my post) so sorry for the mistake off
course the last <number/> should be "pl." not "sg."
I have check it twice and steel managed to miss it.
Some extra info: the singular is implied in export xml and the beginning
of plural is announced with
  <word_number>pl.</word_number> I hope this helps.
I do apologize once again.

This is what im traying to get:

<something_else>
  <form>
      <case>N</case>
      <orth>some_word_N</orth>
      <number>sg.</number>
  </form>
  <form>
      <case>G</case>
      <orth>some_word_G</orth>
      <number>sg.</number>
  </form>
  <form>
      <case>D</case>
      <orth>some_word_D</orth>
      <number>sg.</number>
  </form>
  <form>
      <case>N</case>
      <orth>some_word_N</orth>
      <number>pl.</number>
  </form>
  <form>
      <case>G</case>
      <orth>some_word_G</orth>
      <number>pl.</number>
  </form>
  <form>
      <case>D</case>
      <orth>some_word_D</orth>
      <number>pl.</number>
  </form>

</something_else>
