Why NWDI defines DTR and XI tracks differently?

[Former Member]

I observe 3 differences :

1) pure JAVA track, DTR is used ; PI track, rep is used.

2) pure JAVA track, run-time systems are defined with the admin's password; PI track, no user

credential needed.

3) pure JAVA track can tp *.epa files; I am not sure about PI tracks.

Please help understand. Thanks!
