I read the basic explanation at:

So for testing new data or methods, I definately should use a new 
/mapset/ and not a new /location/ if I intent to use the result later in 
the main project (with the same projection).

So what remains as open question:
How do I get my data from the testing location into the location my main 
project location?
By file system based copying?

Then, I hope that the GRASS 7 vector format will not store the attribute 
table in a direcory separate from the geographica information.

Why does the g.mapset command 
(http://grass.itc.it/gdp/html_grass64/g.mapset.html) not contain a 
remove option?

My scenario doesn't really be that unusual:
