OK I'll replace the following text:

"  turnURI   = scheme ":" host [ ":" port ] [ "?transport=" transport ]
   scheme    = "turn" / "turns"
   transport = "udp" / "tcp" / transport-ext
   transport-ext = 1*unreserved

 <host>, <port> and <unreserved> are specified in [RFC3986].

 Note that the usage of components defined in the [RFC3986] as part of
 a generic hierarchical URI does not mean that a TURN/TURNS URI is
 hierarchical."

by this text:

"  turnURI   = scheme ":" host [ ":" port ] [ "?transport=" transport ]
   scheme        = "turn" / "turns"
   transport     = "udp" / "tcp" / transport-ext
   transport-ext = 1*unreserved
   host          = IP-literal / IPv4address / reg-name
   port          = *DIGIT
   IP-literal    = "[" ( IPv6address / IPvFuture  ) "]"
   IPvFuture     = "v" 1*HEXDIG "." 1*( unreserved / sub-delims / ":" )
   IPv6address   =                            6( h16 ":" ) ls32
                 /                       "::" 5( h16 ":" ) ls32
                 / [               h16 ] "::" 4( h16 ":" ) ls32
                 / [ *1( h16 ":" ) h16 ] "::" 3( h16 ":" ) ls32
                 / [ *2( h16 ":" ) h16 ] "::" 2( h16 ":" ) ls32
                 / [ *3( h16 ":" ) h16 ] "::"    h16 ":"   ls32
                 / [ *4( h16 ":" ) h16 ] "::"              ls32
                 / [ *5( h16 ":" ) h16 ] "::"              h16
                 / [ *6( h16 ":" ) h16 ] "::"
   h16           = 1*4HEXDIG
   ls32          = ( h16 ":" h16 ) / IPv4address
   IPv4address   = dec-octet "." dec-octet "." dec-octet "." dec-octet
   dec-octet     = DIGIT                 ; 0-9
                 / %x31-39 DIGIT         ; 10-99
                 / "1" 2DIGIT            ; 100-199
                 / "2" %x30-34 DIGIT     ; 200-249
                 / "25" %x30-35          ; 250-255
   reg-name      = *( unreserved / pct-encoded / sub-delims )


   <unreserved> <sub-delims> and <pct-encoded> are specified in
   [RFC3986]."

I will also add this in the Acknowledgments section:

"The <port> and <host> ABNF productions have been copied from
 [RFC3986]."


If I do not receive any subsequent comment on this, this text will be in the
next revision of the document, to be released Tuesday 17th.

Thanks.
