Try this:

 <xsl:template match="*">
  <xsl:copy>
   <xsl:copy-of select="@*"/>
   <xsl:apply-templates select="descendant::*[@task=1]/@task"/>
   <xsl:apply-templates select="*"/>
  </xsl:copy>
 </xsl:template>
 
 <xsl:template match="@task">
 <xsl:attribute name="task">1.1</xsl:attribute>
 </xsl:template>

The <xsl:apply-templates select="descendant::*[@task=1]/@task"/> will do
nothing if ther is no descendant::*[@task=1]/@task

You could also use <xsl:apply-templates
select="descendant::*/@task[.=1]"/> but I find the first easy to read
and understand

Hope that this helps you
