SVC 109 by itself might be said to consist of just a table which identifies the extended SVC routines. That table is treated the same as a type 2 SVC, being in the nucleus, and having its name formed by the standard nucleus SVC convention of "IGC" concatenated to the decimal SVC number.
The extended SVC routine that a user provides are expected to be in LPA (which is part of the definition of a type 3 / type 4 SVC).
