XML XSLT 2.0 date format

I have a problem converting dates from XML document using XSLT 2.0.

XML doc view:

<catalog >
  <book id1>
    <title>
      <date> dd-mm-yyyy <date>
    </title>
  </book1>

  <book id2>
    <title>
      <date> dd-mm-yyyy <date>
    </title>
  </book2>
</catalog>

In HTML doc my date must look as ||dd MONTH yyyy||

I'm using XSLT function "format-date" but saxon9he ignores it.
