This Avalon xml code looks very similar to a programm from me i use it to build GUI's for maschines.
Here a xml snippet for a Button:
 <PICTUREBUTTON>
  <SeitenID>Auto</SeitenID>
  <UnterSeiteID/>
  <BackgroundImage>CFTerminal.Bilder.DeckelZuGedreht.gif</BackgroundImage>
  <XLocation>100</XLocation>
  <YLocation>380</YLocation>
  <XSize>75</XSize>
  <YSize>34</YSize>
  <WordPos>1</WordPos>
  <BitMask>512</BitMask>
  <ToggelButton>false</ToggelButton>
  <LEDAnzeigen>false</LEDAnzeigen>
  <LEDBytePos>0</LEDBytePos>
  <LEDBitMask>0</LEDBitMask>
  <DisableByte>1</DisableByte>
  <DisableBitMask>0</DisableBitMask>
 </PICTUREBUTTON>
