NAME

       Regexp::Common::URI::fax -- Returns a pattern for fax URIs.

SYNOPSIS

           use Regexp::Common qw /URI/;

           while (<>) {
               /$RE{URI}{fax}/       and  print "Contains a fax URI.\n";
           }

DESCRIPTION

   $RE{URI}{fax}
       Returns a pattern that matches fax URIs, as defined by RFC 2806.  Under "{-keep}", the following are
       returned:

       $1  The complete URI.

       $2  The scheme.

       $3  The  phone  number,  including  any  possible  add-ons  like  ISDN subaddress, a post dial part, area
           specifier, service provider, etc.

   $RE{URI}{fax}{nofuture}
       As above (including what's returned by "{-keep}"), with the exception  that  future  extensions  are  not
       allowed.  Without  allowing those 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 future extension.
