<Package 
    Name                    = A string between 3 and 50 characters in length that consists of alpha-numeric, period, and dash characters.
    Publisher               = A string between 1 and 8192 characters in length that fits the regular expression of a distinguished name : "(CN|L|O|OU|E|C|S|STREET|T|G|I|SN|DC|SERIALNUMBER|(OID\.(0|[1-9][0-9]*)(\.(0|[1-9][0-9]*))+))=(([^,+="<>#;])+|".*")(, ((CN|L|O|OU|E|C|S|STREET|T|G|I|SN|DC|SERIALNUMBER|(OID\.(0|[1-9][0-9]*)(\.(0|[1-9][0-9]*))+))=(([^,+="<>#;])+|".*")))*". Further, semantic validation ensures that the string is compliant with CertNameToStr Windows API implementation of X.500 rules.
    Version                 = A version string in quad notation, "Major.Minor.Build.Revision".
    ProcessorArchitecture?  = "x86" | "x64" | "arm" | "neutral"
