Just a thought, based on what I think to grasp from what you want to do:

<!-- holds a sequence to two numbers, one with @my.. one with all-->
<xsl:variable name="mytest" select="count(*/@my_atrribute), count(*)" 
as="xs:integer+" />

<!-- choosing between the four possible scenarios. Note: order is 
important! -->
<xsl:choose>
   <xsl:when test="$mytest[1] = $mytest[2]">
      <!-- every child has @my_attribute -->
   </xsl:when>
   <xsl:when test="$mytest[1]">
      <!-- some childs has @my_attribute -->
   </xsl:when>
   <xsl:when test="$mytest[2]">
      <!-- no childs have @my_attribute -->
   </xsl:when>
   <xsl:otherwise>
      <!-- no childs at all -->
   </xsl:otherwise>
<xsl:choose>


As I said, just a thought, and perhaps way easier to write down and/or 
to understand. Like Larry Wall said: there's more than one way to do it.
