well more exactly it is finding the sets of errata_section elements that 
have the same value for their first module_impacted element, and 
returning the first errata_section in each group.

module_impacted elements that are not the first child of an 
errata_section are not considered for the grouping (although probably 
accidentally they are in the sort)
