- * An Annotation object is used as a wrapper for a text attribute value if
- * <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.
