Returns a pattern for fax uris.
use Regexp::Common qw /URI/;
while (<>) {
/$RE{URI}{fax}/ and print "Contains a fax URI.\n";
}
Returns a pattern that matches fax URIs, as defined by \s-1RFC\s0 2806. Under \*(C`{-keep}\*(C', the following are returned: The complete \s-1URI\s0. The scheme. The phone number, including any possible add-ons like \s-1ISDN\s0 subaddress, a post dial part, area specifier, service provider, etc. As above (including what's returned by \*(C`{-keep}\*(C'), with the exception that future extensions are not allowed. Without allowing those future extensions, it becomes much easier to check a \s-1URI\s0 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.
