+/**
+ * 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.
+ *
