Change:
This defines a new URL scheme for QuicTransport, and clarifies the use of "https" for Http3Transport.

Discussion:
6. <ins> NOTE: the URI scheme defintion in this section is provisional and subject to change, especially the name of the scheme. QuicTransport uses the "quic-transport" URI scheme for identifying QuicTransport servers. The syntax definition below uses Augmented Backus-Naur Form (ABNF) RFC5234.  The definitions of "host", "port", "path-abempty", "query" and "fragment" are adopted from RFC3986.  The syntax of a QuicTransport URI SHALL be: This document does not define any semantics to "path-abempty", "query" or "fragment" portions of the URI, nor does it delegate those to the host owners.  Any QuicTransport implementation MUST ignore those until a subsequent specification assigns semantics to those. The "host" component MUST NOT be empty.  If the "port" component is missing, the port SHALL be assumed to be 0. NOTE: this effectively requires the port number to be specified. This specification may include an actually usable default port number in the future. In order to connect to a QuicTransport server identified by a given URI, the user agent SHALL establish a QUIC connection to the specified "host" and "port" as described in connection.  It MUST immediately signal an error to the client if the port value is 0. 7. </ins> QuicTransport supports most of WebTransport features as described in properties. <del> 7. </del> <ins> 8. </ins> QuicTransport satisfies all of the security requirements imposed by OVERVIEW on WebTransport protocols, thus providing a secure framework
