> The high functioning and Asperger's type diagnosis is not about a universal deficit diagnosis

To get an Asperger's diagnosis under the DSM-IV you needed some amount of impairment. "Disorder" is in the title of the DSM, if something isn't conceptualized as a disorder it isn't in there.

The "broader autistic phenotype"- that is, related traits but without impairment- exists but it is not a diagnosis.
