Here in brief are the changes made:

• Sidenotes: they are now full members of a new category: authorial notes. An authorial note is by definition a note (i.e., an out-of-line text fragment) that was provided by the original author of the content (i.e., by the author of the specific FRBR expression).
• Speeches: all speech elements are now available everywhere a container is available. Thus elements such as speech, question and answer are now available in all document types.
• New inline elements: a number of new inline elements have been added to this release: Element lawyer is used to mark the specification of a lawyer. Element opinion is used to specify the opinion of the individual judge within the coram of a judgement. Element signature is used to specify the presence of a signature in the document. Element entity is used to wrap any mention to a concept that is worth being mentioned in the references section. Element date is used to wrap explicit dates in the document (that are not documentDates).
• Judgement-specific and act-specific elements reunited: elements judgementType, judgementTitle and judgementNumber were considered overlapping and redundant with respect to documentType, documentTitle and documentNumber, and thus removed.
• Name changes in metadata elements: Elements within FRBRWork, FRBRExpression , FRBRManifestation, and FRBRItem have now an added FRBR prefix, and thus were turned from this, uri, alias, date, and author to FRBRthis FRBRuri, FRBRalias, FRBRdate, and FRBRauthor.
