the <switchinline>-tag is wrong, because of same menu entry in DRAW and IMPRESS. The entry:
<variable id="feldbf5">Choose Insert <switchinline select="appl"><caseinline select="DRAW">- Fields </caseinline></switchinline>- Page Number </variable>
<variable id="feldbf5">Choose Insert - Fields - Page Number</variable>
