provides a proofreader (often known as grammar checker) for text
An implementation of this service will receive text and has to identify
the sentence end and report all errors found.
An implementation of this service is not limited to grammar checking at all.
It might also check style, used terms etc. Basically it can check every
aspect of a single sentence. Since the text provided is always the complete
paragraph it can also choose to analyze the context of the sentence currently
required to be checked. However error reports need to be limited to the
current sentence.
