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>
