You will need the identity transform with a no-op template:

<xsl:template match="@*|node()">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>

<xsl:template match="x|y|z"/>

Where 'x' 'y' and 'z' are the names of the elements you don't want to
copy through.  Using your thought pattern this would be equivalent to
copy-of select with a predicate (which is of course not possible, as
copy-of select creates an exact copy).
