Hi Mark,

I didn’t expect this to be this hard to parse. 

I understand you are hoping BCP190 will have an effect in the future.

My question is by what means would you measure or determine success? I ask because I (and clearly others on the list) see a pretty big impedance missmatch between reality and BCP190.

Hope this helps to make what l’m asking for clearer.

Cheers Leif

While I understand the points he is making, I'm having a hard time following your line of logic given that BCP 190 does, in fact, codify practices that have largely been applied to URI usage in the past (albeit only in an ad-hoc fashion prior to its publication). It's done a pretty reasonable job of keeping protocols from co-opting parts of the URI space so far, and will ostensibly continue to do so into the future.
