body | The functionality of SML has been subsumed in a more general technical specification called the Business Document Metadata Service Location (BDXL) [BDXL]. This specification is based on DNS, like SML, but is based on a different type of DNS resource records called URI-enabled Naming Authority Pointer records (U-NAPTR) [U_NAPTR], which are defined to support Dynamic Delegation Discovery Service (DDDS). |
