76 * The names should (in general) answer the question "what is wrong?" with an answer that begins "There is a ..."
77 * e.g. "There is a INCORRECT_CPL_HASH"
78 * "There is a MISSING_ASSET"
80 * In general the pattern should be <negative-adjective> <noun>.
81 * Some <negative-adjective>s are:
83 * - INCORRECT: something, which could have any value, is wrong.
84 * - INVALID: something, which should only be one of a set of values, is not in the set, or some preformatted
85 * quantity (e.g. XML) is in the wrong format.
86 * - MISMATCHED: two things, which should be the same, are not.
87 * - EMPTY: something, which should have a value, has no value.
88 * - MISSING: something, which should be present, is not.
89 * - UNEXPECTED: something, which is present, should not be.
90 * - FAILED: some part of the verification failed in some serious way.
92 * Comments should clarify meaning and also say which of the optional fields (e.g. file)
93 * are filled in when this code is used.
