Re: CPIM and URIs

I was worried about URIs that contain the string "%40", the escaped
version of '@'.  The point I tried to make is that with your syntax,
one cannot make use of a generic URI scheme specific part decoder.
This is because '@' and "%40" both translate into the same code, so
that '@' no longer can be relied on to separate the local part from
the domain.  Java provides the java.net.URI class that includes a
method which supplies the decoded scheme specific part, the string
that results after replacing each escaped sequence with its ASCII
value.

Let me emphasize, this is not a big issue with me.  I just wanted to
note one downside of your syntax.

On another topic, an example I gave was flawed.

It should have been the following.

      a@[@\[@]

      "a@["@[@]
