I do notice that the IEFSSAL mapping has a flag added in 2009: SSALXTIO EQU X'40' Subsystem supports XTIOT, * uncaptured UCBs, and DSABs above * above the line. This sounds like enabling infrastructure, and that the individual JESs may or may not support XTIOT. You don't say how your attempt fails (works, but creates a normal TIOT entry?). The comment on SSALXTIO says "The flag will be copied to the DSAB and used by OPEN to ensure that subsystem DDs using the above functions are not opened unless they explicitly support them.", which sounds as though there should be a failure rather than a fallback if there's no support. But this is all speculation...
