Change this key to

<xsl:key name="oldID" match="option" use="@oldID" />

and then change this for-each to:

<xsl:for-each select="$Definitions">
 <xsl:value-of select="count(key('oldID',$current))" />
</xsl:for-each>

You have a few other typo's to fix (if you code matches your example)
but that should be it.
