    Don't warn if an unknown element is used in an expression
    
    The type will be resolved at runtime...
    
    For example, we can do this now without getting a warning:
    
    <match target="font">
      <test name="scalable" compare="eq">
        <bool>false</bool>
      </test>
      <edit name="pixelsizefixupfactor" mode="assign">
        <divide>
          <name target="pattern">pixelsize</name>
          <name target="font"   >pixelsize</name>
        </divide>
      </edit>
      <edit name="matrix" mode="assign">
        <times>
          <name>matrix</name>
          <matrix>
            <name>pixelsizefixupfactor</name> <double>0</double>
            <double>0</double> <name>pixelsizefixupfactor</name>
           </matrix>
        </times>
      </edit>
      <edit name="size" mode="assign">
        <divide>
          <name>size</name>
          <name>pixelsizefixupfactor</name>
        </divide>
      </edit>
    </match>
    
    Previously the last edit was generating:

commit 51b0044648e00025cf20014b19aaceed7beeed75
Author: Behdad Esfahbod <behdad@xxxxxxxxxx>

    Allow target="font/pattern/default" in <name> elements
    
    Based on idea from Raimund Steger.
    
    For example, one can do something like this:
    
    <match target="font">
      <test name="scalable" compare="eq">
        <bool>false</bool>
      </test>
      <edit name="pixelsizefixupfactor" mode="assign">
        <divide>
          <name target="pattern">pixelsize</name>
          <name target="font"   >pixelsize</name>
        </divide>
      </edit>
      <edit name="matrix" mode="assign">
        <times>
          <name>matrix</name>
          <matrix>
            <name>pixelsizefixupfactor</name> <double>0</double>
            <double>0</double> <name>pixelsizefixupfactor</name>
           </matrix>
        </times>
      </edit>
    </match>
    
    Part of work to make bitmap font scaling possible.  See thread
