In XSLT 2.0 (correcting your XML input)

<testnode>
  <xsl:attribute name="att1" select="testnode/@att1" separator=","/>
  <xsl:attribute name="att2" select="testnode/@att2" separator=","/>
</testnode>

In 1.0

<testnode>
  <xsl:attribute name="att1">
    <xsl:for-each select="testnode">
      <xsl:value-of select="@att1"/>
      <xsl:if test="position()!=last()">,</xsl:if>
etc.
