difference between dfs:myFields and my:myFields

[Stephan Steiner]

Hi

I noted that when I create a forum that uses a Database as datasource, all
datasources I create manually have a my: prefix in the UI, and in scripting,
I have to access them via dfs:myFields/my:myvariable, whereas if I don't
have a database, in the UI I just have the name of the variable in the list
of datasources without my: prefix, and in a script I have to access them
using my:myFields/my:myvariable

Is there a reason for that difference?
