  Hi,

	"Element menuchoice content does not follow the DTD"

 Remove menuchoice tags on line 61 (digikam/using-mainwindow-
imageview.docbook): 

<menuchoice>
  <shortcut><keycombo action="press"><keycap>F3</keycap></keycombo></shortcut>
  <menuchoice><guimenu>View</guimenu><guimenuitem>Preview Image</
guimenuitem></menuchoice>
</menuchoice> 

to

<menuchoice>
  <shortcut><keycombo action="press"><keycap>F3</keycap></keycombo></shortcut>
  <guimenu>View</guimenu><guimenuitem>Preview Image</guimenuitem>
</menuchoice>

  With a single key the keycombo tag is not necessary...  This does not 
infringe anything :) 

  Regards
  Toni
