[Openid-specs-ab] User input normalization and parsing

[John Bradley]

Per my other email to the list Java is doing the correct thing there is no authority segment for acct: it is all path.  

If it were acct://boo@foo.com then it would parse as a higher-part and find the host and user.   That is a acct URI issue.

Specifically, when using the Regex in Appendix B of RFC3986 (and several derivatives such as that used by Spring's UriComponentsBuilder), the "path" component seems to eat things that it shouldn't. For instance, with the input "joe at example.com", I get the entire string put into the "path" component and everything else null. Similar thing happens with the "acct:juliet%40capulet.example at shoppingsite.example.com" example, with the "acct" being parsed as the scheme and everything else getting dumped into the path.

And if you're working in Java, can you point me at your code or the library that you're using to do it? (Note that Java's built-in URI parser falls over for other reasons.)
