Since the XML code is already a "decompiled" version, people will likely just have to create new utilities.

For example, a snippet from the default PCF:

<ITEM id="758">
  <BUTTON>
    <Position>
      <PosXPosY>177 146</PosXPosY> 
    </Position>
    <Dimension>
      <WidthHeight>37 39</WidthHeight> 
    </Dimension>
    <TextColor>
      <RGB>255 255 255</RGB> 
    </TextColor>
    <BGColor>
      <RGB>170 170 170</RGB> 
    </BGColor>
    <TextColorPressed>
      <RGB>0 0 0</RGB> 
    </TextColorPressed>
    <BGColorPressed>
      <RGB>0 0 0</RGB> 
    </BGColorPressed>
    <Font>
      <NameSize>STANDARD 10</NameSize> 
    </Font>
    <BitmapNormal id="37" /> 
    <BitmapPressed id="38" /> 
    <Label id="796" /> 
    <UDP_FunctionID>29</UDP_FunctionID> 
     <ActionList id="395" /> 
   </BUTTON>
   <TextAlignment>
     <HorizontalVerticalAlignment>CENTER CENTER</HorizontalVerticalAlignment> 
   </TextAlignment>
</ITEM>
