      TAS, TAM and BTIC Relationship Enrichment

      A "type" attribute will be added to the relationship record for underlyingInstruments and overlyingInstruments to indicate whether the underlying is a "TAS," "TAM," or "BTIC". Type will be "null" if the underlying is none of these.

      Example of relationships for TAS product:

      {
        "_embedded" : {
          "relationships" : [ {
            "marketSide" : null,
            "legNumber" : null,
            "ratio" : null,
            "type" : "TAS",
            "_links" : {
              "underlyingInstrument" : {
                "href" : "_/v1/instruments/UNEE4CUUUUUU"
              },
              "overlyingInstrument" : {
                "href" : "_/v1/instruments/A5JMRD555555"
              }
            }
          } ]
        },
        "_links" : {
          "self" : {
            "href" : "_/v1/instruments/A5JMRD555555/underlyings?page=0&size=20"
          }
        },
        "_metadata" : {
          "size" : 20,
          "totalElements" : 1,
          "totalPages" : 1,
          "number" : 0,
          "type" : "page"
        }
      }
