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.
