Why can the OSC import a Script Definition Language [SDL] File?
The Script Definition Language [SDL] was designed originally to verify that an RTI was compliant with the HLA/RTI specification. SDL is a fully-functional language including looping, branching, and subroutines. Furthermore, SDL supports the invocation of any RTI service, and can handle any federate callback. In short, SDL is much more capable and complex than the OSC. However, the OSC provides a simpler mechanism for producing SDL files.
