Also, as you write below, Namespace may be *not* a URL
and we already have plenty of legacy namespaces which
are *not* URLs.

Exactly. But it is not 'worse is better'. It is simply 'worse'. Adding one
level of indirection solves that. And many other problems as well.

namespaceURI is a unique hidden property, attached to every tag.
As it is written in a Namespace documentation.

I got tired with this RDDL thread, I think it goes nowhere,
so I decided that instead of repeating the same stuff
over and over again, I would spend some time
implementing the simple alternative to RDDL that would not
abuse any existing XML paper, would not provide any
lock-ins and would work / scale if somebody would
decide to use it.
Not that I'm happy spending time on that ( because I don't use
namespaces ), but I feel that if not doing that, people may
think that they really need these 'arcroles' for something. How
easy it would be to create a mafia around 'my RDDL' -
that's another story.
Give me a few days / weeks (I start working
fulltime next Monday, so I would have only weekend
evenings now) and then I wish this thread would become
I may use HGRAB to steal some stuff from rddl.org, but
because there is no robots.txt - that should be legal thing
to do ;-)
Talk to you later. The existance of open-minded people
in this world is the only thing that protects me from
complete madness ;-)
