I was looking at the ABNF for this URN and the extensibility seemed slight wrong. We allow identifiers to be made out the characters ( ALPHA / DIGIT / "-" / “.” ) but component are restricted to ( ALPHA / DIGIT ). I don’t see any reason for this and suspect it was just a simple oversight. I have submitted a PR make the characters allowed in an component be the same as the identifier. The PR also just simplifies the ABNF and allows future URN to be defined using more “:” after the first subtype. The PR is at https://github.com/jariarkko/core-dev-urn/pull/3 Let me know if there are any problems with this Thanks, Cullen
