I'm going to assume you are using XSL(T) standard as defined by W3C
although I have a suspicion that you are using the language called
XSL in IE5 (which is not the same thing at all).

   <xsl:for-each select="cmdTargets">
   <Target>
   <xsl:for-each select="@*">
   <xsl:copy><xsl:value-of /></xsl:copy>
   </xsl:for-each>
   </Target>
   </xsl:for-each>

xsl:value-of requires a select argument (select="." here)


   How could I modify this so that any attributes named "ID" and "Version" are
   not copied to the output?

this would work:

 <xsl:for-each select="@*[not(self::ID or self::Version)]">

But you can do it more simply without the for-each, copy and value-of


   <xsl:for-each select="cmdTargets">
   <Target>
   <xsl:copy-of select="@*[not(self::ID or self::Version)]"/>
   </Target>
   </xsl:for-each>
