This step checks the validity of an e-mail address according to a valid e-mail address format. The step supports verification of the top level domain (TLD). The TLD can contain characters and numbers and must start with a character. Lower level domains respect letter digit hyphen (LDH) syntax and can start with a number. A hyphen is allowed within the domain portion only. If an error is detected (EML_ADDRESS, EML_TLD or EML_NULL), an empty value is stored in both outputs outName and outEmail.
