$default_port
$default_port
Scheme's default port (integer). If an explicit port number is specified that coincides with the default port, it will be elided.
Validates tel (for phone numbers).
The relevant specifications for this protocol are RFC 3966 and RFC 5341, but this class takes a much simpler approach: we normalize phone numbers so that they only include (possibly) a leading plus, and then any number of digits and x'es.
