Wix Heat harvest: removing directories containing filtered components with transform

I have the following snippet of a .wxs(Ids ommitted) outputted from WiX harvest.

        <Directory Id="" Name="tr">
            <Component Id="" Guid="*">
                <File Id="" KeyPath="yes" Source="$(var.SourceDir)\tr\ZedGraph.resources.dll" />
            </Component>
        </Directory>
        <Directory Id="" Name="zh-cn">
            <Component Id="" Guid="*">
                <File Id="" KeyPath="yes" Source="$(var.SourceDir)\zh-cn\ZedGraph.resources.dll" />
            </Component>
        </Directory>
        <Directory Id="" Name="zh-tw">
            <Component Id="" Guid="*">
                <File Id="" KeyPath="yes" Source="$(var.SourceDir)\zh-tw\ZedGraph.resources.dll" />
            </Component>
        </Directory>
    </DirectoryRef>

And the following transform will remove the components but leaves the empty directory elements. How can I remove them as well? Given that I do not want to blanket remove all directory elements. Ideally, I would like to match them based on containing the component Id that is returned from the search.

<xsl:key name="zedResource-search" match="wix:Component[contains(wix:File/@Source, 'ZedGraph.resources.dll')]" use="@Id" />
<xsl:template match="wix:Component[key('zedResource-search', @Id)]" />
<xsl:template match="wix:ComponentRef[key('zedResource-search', @Id)]" />

This question is similar, but uses the directory names which i would like to avoid adding a search for each of these because there are quite a few language variants.

One way to do this is use a separate template to match the Directory element where all the child Component elements are in the key. You do this comparison with a count

 <xsl:template match="wix:Directory[count(wix:Component) 
                                     = count(wix:Component[key('zedResource-search', @Id)])]" />

Alternately, you can say you want to remove Directory which don't have a Component ref that are not in the key (so, a double negative)

<xsl:template match="wix:Directory[not(wix:Component[not(key('zedResource-search', @Id))])]" />
