Right.

At the moment I have here tmdm. 'dm' reminded me too much of
'Drogeriemarkt', a drug store chain in Austria. But I'm not
religious about that ;-)

Will have a look, ok.

I have already changed them to 'true' | 'false'.

Just to be clear on this. We have the following cases:

   rumsti                 .... this is interpreted as item identifier
   http://rumsti.com      .... this is interpreted as subject identifier (indication)
   http://rumsti.com ~    .... the same, just more explicit
   some:rumsti            .... also subject identifier
   some:rumsti ~          .... the same, more explicit
   http://rumsti.com =    .... subject locator
   some:rumsti =          ...  still subject locator

Yes, the text can be more streamlined to say exactly this.

Definitely 'subject locator'.
