// The comments for the structs and fields can be used from go-resful to

// Common string formats
// ---------------------
// Many fields in this API have formatting requirements. The commonly used
// formats are defined here.
//
// C_IDENTIFIER:  This is a string that conforms to the definition of an "identifier"
//     in the C language. This is captured by the following regex:
//         [A-Za-z_][A-Za-z0-9_]*
//     This defines the format, but not the length restriction, which should be
//     specified at the definition of any field of this type.
//
// DNS_LABEL:  This is a string, no more than 63 characters long, that conforms
//     to the definition of a "label" in RFCs 1035 and 1123. This is captured
//     by the following regex:
//         [a-z0-9]([-a-z0-9]*[a-z0-9])?
//
// DNS_SUBDOMAIN:  This is a string, no more than 253 characters long, that conforms
//      to the definition of a "subdomain" in RFCs 1035 and 1123. This is captured
//      by the following regex:
//         [a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*
//     or more simply:
//         DNS_LABEL(\.DNS_LABEL)*
//
// IANA_SVC_NAME: This is a string, no more than 15 characters long, that
//      conforms to the definition of IANA service name in RFC 6335.
//      It must contains at least one letter [a-z] and it must contains only [a-z0-9-].
//      Hypens ('-') cannot be leading or trailing character of the string
//      and cannot be adjacent to other hyphens.
