=head1 NAME
Regexp::Common::URI::fax -- Returns a pattern for fax URIs.
=head1 SYNOPSIS
use Regexp::Common qw /URI/;
while (<>) {
/$RE{URI}{fax}/ and print "Contains a fax URI.\n";
}
=head1 DESCRIPTION
=head2 $RE{URI}{fax}
Returns a pattern that matches I<fax> URIs, as defined by RFC 2806.
Under C<{-keep}>, the following are returned:
=over 4
=item $1
The complete URI.
=item $2
The scheme.
=item $3
The phone number, including any possible add-ons like ISDN subaddress,
a post dial part, area specifier, service provider, etc.
=back
=head2 C<$RE{URI}{fax}{nofuture}>
As above (including what's returned by C<{-keep}>), with the exception
that I<future extensions> are not allowed. Without allowing
those I<future extensions>, it becomes much easier to check a URI if
the correct syntax for post dial, service provider, phone context,
etc has been used - otherwise the regex could always classify them
as a I<future extension>.
