tables. +In these tables 'Server' refers to acting in the GATT server role, and 'Client' refers to acting in the GATT client role for the specific +service. +If a profile role depends on another profile that depends on a service, then that dependency is implicitly also applied to that profile. +For example, if the CAP Acceptor uses the BAP Unicast Server role, then the requirements on the ASCS Server and PACS Server also apply to the CAP Acceptor. + +The dependencies for Stream Control (BAP) are in the following table. + +.. table:: BAP dependencies + :widths: auto + :align: center + +
