You can always write your own DTD-specific attribute filter, e.g.:

<xsl:template match="@*">
  <xsl:choose>
   <xsl:when test="self::attname_1 and
                   string(.) = 'default_value'"/>
   <xsl:when test="self::attname_2 and
                   string(.) = 'annother_default_value'"/>
   <xsl:otherwise>
     <xsl:copy-of select="."/>
   </xsl:otherwise>
  </xsl:choose>
</xsl:template>

This is a common technique for transforms that are essentially identity 
transforms and that need to not include defaulted attributes in the output.

But note that as Ken says you still cannot distinguish a defaulted 
attribute from one whose specified value happens to be the default.

Cheers,
