/** |
|
35 |
* RDNs are a set of {attribute = value} assertions. Some of those |
|
36 |
* attributes are "distinguished" (unique w/in context). Order is |
|
37 |
* never relevant. |
|
38 |
* |
|
39 |
* Some X.500 names include only a single distinguished attribute |
|
40 |
* per RDN. This style is currently common. |
|
41 |
* |
|
42 |
* Note that DER-encoded RDNs sort AVAs by assertion OID ... so that |
|
43 |
* when we parse this data we don't have to worry about canonicalizing |
|
44 |
* it, but we'll need to sort them when we expose the RDN class more. |
|
45 |
* <p> |
|
46 |
* The ASN.1 for RDNs is: |
|
47 |
* <pre> |
|
48 |
* RelativeDistinguishedName ::= |
|
49 |
* SET OF AttributeTypeAndValue |
|
50 |
* |
|
51 |
* AttributeTypeAndValue ::= SEQUENCE { |
|
52 |
* type AttributeType, |
|
53 |
* value AttributeValue } |
|
54 |
* |
|
55 |
* AttributeType ::= OBJECT IDENTIFIER |
|
56 |
* |
|
57 |
* AttributeValue ::= ANY DEFINED BY AttributeType |
|
58 |
* </pre> |
|
59 |
* |
|
60 |
* Note that instances of this class are immutable. |
