Is this part of the disorder?
It is a facet of OCPD. OCPD is not OCD or obsessive compulsive disorder. OCPD is obsessive compulsive personality disorder. Sounds the same but very different. People with OCD are often aware that their obsessions are abnormal, but are compelled to perform them anyway, like hand washing. People with obsessive compulsive personality disorder, however, believe their need for strict order and rules takes precedence over the activity at hand.

According to the DSM, OCPD is a mental disorder where an individual strives for success by using rules to get there. Perfection is the ultimate goal of the OCPD person, and failure is seen as unacceptable. These rules seem necessary to the personality- but accordance to them actually hinders their life and causes more stress when the unrealistic rules cannot be maintained- especially by others. It causes great difficulty in their interpersonal relationships.
Many people with OCPD were taught these rules in childhood and suffer trained thought (brainwashing.)
