Index marks in speech dispatcher.

[x mash]

Hi folks! I'm using index marks for my project. How set it correctly. For 
example
I'm doing like that:

spd_execute_command_with_reply( m_connection, "SET SELF SSML_MODE on", & reply 
);
spd_send_data_wo_mutex( m_connection, "<speak>Hello, <mark name=\"mark1\"/> how
does it work?</speak>", SPD_NO_REPLY );
spd_execute_command_with_reply( m_connection, "SET SELF SSML_MODE off", & reply
);
spd_execute_command_with_reply( m_connection, "\r\n.", & reply );

it's most advanced idea what I have, but didn't work. Help!!! How can I set 
index
marks in SSIP mode, or how is correctly switched to SSML mode? Thank you.
