constructors: Annotation(Object value)
methods: getValue(), toString()

An Annotation object is used as a wrapper for a text attribute value if the attribute has annotation characteristics. These
characteristics are:

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.
The attribute or its value usually do no longer apply if the underlying text is changed.

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).

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.
