I'll answer here for both 1. and 2. There is no equivalent of the four
"variable stack" services of Acceleo 2 : push(), pop(), put() and get().
In Acceleo 3 the variables are explicit, and the generation should then
be rethought in order to use explicit variables.
That would mean passing the result of "doValidate()" explicitely to the
template using "get('validationResult')" from the template that does
"put('validationResult', doValidate())".
Granted, this is easier said than done with UML2Java or other "big"
modules ... but that should greatly clarify these modules and ease their
maintenance.

"Split" hasn't been implemented in Acceleo 3, you could use
"tokenize('.')" instead for this use case.
