Hi,

I'm joining the discussion a bit late, but it seems to me that allowing something that looks
like a URL that's not a URL is a bad idea.  This seems to have introduced unnecessary
confusion into namespaces:  It makes an accompanying explanation and admonishment necessary
("Don't assume there's anything at this 'not-URL' ").  From a software engineering point of
view,  I think it'd be better to chose something that doesn't require the extra documentation
- Instead of saying, "Watch out for the problem here...", we should not create the problem in
the first place.

I think that the Java standard is very good. I don't think that it's unfriendly towards
non-Java implementations:  it is after all, only a standard, and not hardcoded into the
language.  The main problem with it is that users who do not have a measure of authority at
their organization can have problems.  So, for example, I've released some open source code
with the package name:

org.acm.robb

...because I have the e-mail address robb@acm.org.  That works until the ACM decides to put a
host named "robb" on the acm network.  (OK, that may not happen :) - but the point is valid.)

So, I'm for a clear format, maybe Java-like, that --doesn't-- resemble a URL, that solves the
above issue.
