Ok, sorry I forgot about the Thurstone example as I was focusing on Path 
Analysis example when reading the sem doc.

I understand this is a model taken from another source.

In the model specification I notice a F4->F1, F4->F2, F4->F3.

This is something I do not understand.

In a "normal" case where one is iterested in the factorial validity of the 
indicator variables, would it be appropiate to use the same specification 
just omitting the above links?

Saluti,
