// ---------------------
// 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.
// ObjectMeta is metadata that all persisted resources must have, which includes all objects
// users must create.
