Unfortunately, attribute sets cannot be added conditionally.  I've 
wanted to do this myself in the past.

If you change the attribute set to a called template (no other 
changes), then you can put the call to the template in the if.

Doing so takes away the cumulative nature of attribute sets in an 
import/include tree, but if that isn't a concern for you, then a 
called template should do the trick.

So, change:

  <xsl:attribute-set name="my:background-gray">
    <xsl:attribute name="background-color">#dddddd</
    <xsl:attribute name="border">#222222</
  </xsl:attribute-set>

to:

  <xsl:template name="my:background-gray">
    <xsl:attribute name="background-color">#dddddd</
    <xsl:attribute name="border">#222222</
  </xsl:template>

and use:

   <fo:table-row hyphenate="true">
      <xsl:if test="position() mod 2 = 0">
        <xsl:call-template name="my-background-gray"/>
      </xsl:if>
   ....

I hope this helps.
