Thank you Jason, so I was only looking at it from my practical experience not from the theory behind it. And I thought the fragment was also part of what Regex::Common URI matches. I just checked and probably mixed something up when reading the source last time. So this brings me back to my problem to find a constrain that handles the http webadresses a user could type. For me that should include the fragment and doesn't need necessarily the https? scheme. For now I would suggest to make a custom Constraint out of it which doesn't need to be part of the main formfu distribution. What do you think Carl?
