Just count the difference of those from where you are less those that 
are before the closest group before:

 <xsl:element name="concat(name(.),
       1 + count(preceding-sibling::DifferentialDiagnosis)
         - 
count(preceding-sibling::Category[1]/preceding-sibling::DifferentialDiagnosis))">

I hope this helps.
