Need clarification on document UM10204 (I2C-bus specification and user manual)

I'm seeking some clarification on section 3.1.17 Device ID.

 

In this section is lists 7 steps to access the Device ID.

 

In step 2 it notes "The master sends the Reserved Device ID I2C-bus address followed by the R/W bit set to ‘0’ (write): ‘1111 1000’."

 

As there is nothing else in the document that explains what the "Reserved Device ID" is, I just wanted to check that I literally have to enter "1111 1000" and it is not "1111 1XXX" table 3 in section 3.1.12 Reserved addresses, where it indicates that XXX can be any value. So a little confused.

 

I look forward to getting clarification.

 

Thanks
