* attribute description, with {@code objectClass} first, then all user

|
* supported by this implementation.
|
* <p>
|
* A {@code TreeMapEntry} stores references to attributes which have been added
|
* using the {@link #addAttribute} methods. Attributes sharing the same
|
* attribute description are merged by adding the values of the new attribute to
|
* the existing attribute. More specifically, the existing attribute must be
|
* modifiable for the merge to succeed. Similarly, the {@link #removeAttribute}
|
* methods remove the specified values from the existing attribute. The
|
* {@link #replaceAttribute} methods remove the existing attribute (if present)
|
* and store a reference to the new attribute - neither the new or existing
|
* attribute need to be modifiable in this case.
