/**
* An Annotation object is used as a wrapper for a text attribute value if
* the attribute has annotation characteristics. These characteristics are:
* <ul>
* <li>The text range that the attribute is applied to is critical to the
* semantics of the range. That means, the attribute cannot be applied to subranges
* of the text range that it applies to, and, if two adjacent text ranges have
* the same value for this attribute, the attribute still cannot be applied to
* the combined range as a whole with this value.
* <li>The attribute or its value usually do no longer apply if the underlying text is
* changed.
* </ul>
*
* An example is grammatical information attached to a sentence:
* For the previous sentence, you can say that "an example"
* is the subject, but you cannot say the same about "an", "example", or "exam".
* When the text is changed, the grammatical information typically becomes invalid.
* Another example is Japanese reading information (yomi).
*
* <p>
* Wrapping the attribute value into an Annotation object guarantees that
* adjacent text runs don't get merged even if the attribute values are equal,
* and indicates to text containers that the attribute should be discarded if
* the underlying text is modified.
