Rest API payloads (Inbound/Outbound) to remove ListOf entity tags.

Hi Experts,

I am checking for the possibilities to remove the ListOf Tages (entities) for the REST Inbound/Outboud payload. The external team feels if should be array parameter '[' and ']' instead of ListOf.

I could see Siebel using the REST as conversion of xml datastructure and that by default brings the ListOf tags when it is array. Is there a way(any user property or something) so the external system received payload from siebel without ListOf and use array parenthesis '[' to be more Restful services.
