The <NestedParties> component block is identical to the <Parties> Block. It is used in other component blocks and repeating groups when nesting will take place resulting in multiple occurrences of the <Parties> block within a single FIX message. Use of <NestedParties> under these conditions avoids multiple references to the <Parties> block within the same message which is not allowed in FIX tag/value syntax.
