[DDI-SRG] Namespaces and standard prefixes

[Joachim Wackerow]

You found it! That was the test, if anybody reads the suggestion :) .
No, just joking. This suggestion can be surely improved.

The issue is not big, but it should be discussed and the agreed solution 
should be in the published version. I know, this is not new. But I did 
always change the prefixes for my instances and realized now that Pascal 
did the same.
