-/* For compliance with RFC 2253, RFC 3280 and RFC 4630, we choose to
- * use the NAME=STRING form, rather than the OID.N.N=#hexXXXX form,
- * when both of these conditions are met:
- * 1) The attribute name OID (kind) has a known name string that is
- * defined in one of those RFCs, or in RFCs that they cite, AND
- * 2) The attribute's value encoding is RFC compliant for the kind
- * (e.g., the value's encoding tag is correct for the kind, and
- * the value's length is in the range allowed for the kind, and
- * the value's contents are appropriate for the encoding tag).
- * Otherwise, we use the OID.N.N=#hexXXXX form.
- *
- * If the caller prefers maximum human readability to RFC compliance,
- * then
- * - We print the kind in NAME= string form if we know the name
- * string for the attribute type OID, regardless of whether the
- * value is correctly encoded or not. else we use the OID.N.N= form.
- * - We use the non-hex STRING form for the attribute value if the
- * value can be represented in such a form. Otherwise, we use
- * the hex string form.
- * This implies that, for maximum human readability, in addition to
- * the two forms allowed by the RFC, we allow two other forms of output:
- * - the OID.N.N=STRING form, and
- * - the NAME=#hexXXXX form
- * When the caller prefers maximum human readability, we do not allow
- * the value of any attribute to exceed the length allowed by the RFC.
- * If the attribute value exceeds the allowed length, we truncate it to
- * the allowed length and append "...".
- * Also in this case, we arbitrarily impose a limit on the length of the
- * entire AVA encoding, regardless of the form, of 384 bytes per AVA.
- * This limit includes the trailing NULL character. If the encoded
- * AVA length exceeds that limit, this function reports failure to encode
- * the AVA.
- *
- * An ASCII representation of an AVA is said to be "invertible" if
- * conversion back to DER reproduces the original DER encoding exactly.
- * The RFC 2253 rules do not ensure that all ASCII AVAs derived according
- * to its rules are invertible. That is because the RFCs allow some
- * attribute values to be encoded in any of a number of encodings,
- * and the encoding type information is lost in the non-hex STRING form.
- * This is particularly true of attributes of type DirectoryString.
- * The encoding type information is always preserved in the hex string
- * form, because the hex includes the entire DER encoding of the value.
- *
- * So, when the caller perfers maximum invertibility, we apply the
- * RFC compliance rules stated above, and add a third required
- * condition on the use of the NAME=STRING form.
- * 3) The attribute's kind is not is allowed to be encoded in any of
- * several different encodings, such as DirectoryStrings.
- *
- * The chief difference between CERT_N2A_STRICT and CERT_N2A_INVERTIBLE
- * is that the latter forces DirectoryStrings to be hex encoded.
- *
- * As a simplification, we assume the value is correctly encoded for
- * its encoding type. That is, we do not test that all the characters
- * in a string encoded type are allowed by that type. We assume it.
