BTW, it might interest the reader to know that, despite all the hype about DSM-5, Medicare/Medicaid do not use it for diagnosis, in part due to the controversy regarding a great many disorders. They use ICD-10-CM instead. (https://www.cms.gov/Medicare/Coding/ICD10/index.html)

Dyslexia in the ICD-10 more closely resembles Shaywitz's recommendations (and the DSM-IV):

http://www.icd10data.com/ICD10CM/Codes/F01-F99/F80-F89/F81-/F81.0

So if a clinician says DSM-5 doesn't allow them to give a dyslexia or dysgraphia diagnosis, you may wish to ask them to consider ICD-10 diagnostic criteria.
