SCP: Template file variants

Imported from previous forum

I’m using SCP 1.1 Level 2 were server and clients download a template file from a common web site. I’ve noticed that some FAST implementations need to have Hello and Alert messages define in the template file, while other implementations do not. My reading of the SCP document is that this is ambiguous? Is my reading correct? Is there a recommended practice?

Do people normally supply different variants of the templates for different implementations?
