Subject: Re: [xdi] colon for values only?

Markus, I thought about this and started working on it in the ABNF. The key challenge with not using colons is: a) they are the standard delimiter in IPv6 addresses, and b) they align nicely with URI scheme syntax.

Since they are not allowed as the first character in any subsegment EXCEPT the terminating literal subsegment, it shouldn't be hard to exclude them in parsing, no?

While doing some implementation work I ran into a parsing challenge around colons

We have been using them to indicate a value, but we're also using them in UUIDs.
To me this creates ambiguity in the parsing process.

So I propose to use colons ONLY for values.
One idea would then be to use dots . instead in UUIDs, since dots have no syntactical meaning in XDI anyway.

This is completely orthogonal to the current discussions around paired vs. leading vs. trailing symbols.

Example with dots in UUIDs according to "Second Strawman":
Joseph would your version look like this? Please correct
