Re: [Uri-review] URI scheme registration request

[John Wason <[e-mail]>]

Is it possible to register a "wildcard" or have an understanding that 
the scheme can be appended with the transport type?  Subversion uses 
"svn+ssh" to specify an ssh tunnel.  This format seems to be used 
occasionally in practice. Because the different transports can point to 
completely different resources on the same host I am not sure having the 
transport in the query portion is the correct solution.
