Example 13 does not comply to the schema, because of `sdpi:Epochs`

[leon1995]

the extension in example 13 should be

<sdpi:Epochs Version="5">
  <!-- non-slewing adjustment at 1 pm (1733317200000) in Epoch 4 shifted time back
                     to 10 am starting epoch 5 (1733306400000) -->
  <sdpi:Epoch>
    <sdpi:Epoch Version="4" Timestamp="1733317200000" Offset="-PT3H" />
  </sdpi:Epoch>
  <!-- non-slewing adjustment at 7 am (1733295600000) in epoch 3 shifted time
                     forward to 11 am starting epoch 4 (1733310000000) -->
  <sdpi:Epoch>
    <sdpi:Epoch Version="3" Timestamp="1733295600000" Offset="PT4H" />
  </sdpi:Epoch>
</sdpi:Epochs>

which is kinda weird. In my opinion the schema should be adopted

Thanks @leon1995 ; that's my bug in the schema; the example is the intended xml.

PR #521 should resolve.
