A new feature allows you to reference any section of the record (offset,length) even if it does not correspond to a field.
It can be very useful to be able to write a filter (or a conditional expression in general) that directly references a section of the record even if this section does not correspond to a field. For conditional expressions we now allow retrieving a portion of a record as it would be a CT_ARRAY field. The new function syntax is FIELD(offset,size) and evaluates as a CT_ARRAY field with length size containing the portion of the current record starting at offset offset.
