From what I understand of the diagnostic criteria, the only marked difference is a significant language delay for an autims diagnosis.
Which is correct at face value, but the manifestation of the two sets of criteria are entirely different as it's written in the expanded text; the delay in the acquisition of speech usually comes with a whole slew of other symptoms along for the ride, as well as a different manifestation of the social impairments and repetitive behaviours. It's more detailed than the criteria themselves.
The OP is correct: Asperger's and Autism are two different disorders that share some overruling outcomes, but are different in how the outcome is reached. OCD and Social Phobia are both Anxiety Disorders, as they both cause Anxiety, but they both manifest differently.
Professionals like Attwood tend lump them together as the treatment is the same for both, just as it is for many Anxiety Disorders.
