Nevertheless, over the course of

years a certain structure has been developed. Textbooks of Private

International Law will usually contain a discussion of general principles of

Private International Law, such as renvoi, classification or the preliminary

question. In addition, the rules relevant for various types of legal

relationships will be discussed. Sometimes such discussion in respect of the

various types of legal relationships will only deal with the choice of law

rules, but nowadays such discussion will also deal with jurisdiction and

recognition and enforcement, as there will often be specific rules in respect

of a particular legal relationship. The textbook will also contain general

principles.
