Hi Luc,
There is no ternary operator in OCL. You have to use a regular "if else
endif" :
fullTableName : String = item.name + (if (isAuditTable) then '_AUDIT'
else '_NORMAL' endif);

Yup, Acceleo is an implementation of the MOF Model to Text standard ...
but this itself heavily depends on OCL. Most of the "expressions" you
will use in Acceleo are in fact OCL expressions (augmented with our own
standard library operations).
We provide in the documentation (Help > Help Contents > Acceleo Model to
Text) a reference guide of the standard OCL operations. Though this
guide still sports some typos, you can use it in order to find your way
around OCL.
