yes,  new README says

1.4.6. allow_uri(basename, pseudo-variable)

     * pseudo-variable - Any pseudo-variable defined in OpenSER.

and includes examples:

...
if (allow_uri("basename", "$rt)) {  // Check Refer-To URI
        t_relay();
};
if (allow_uri("basename", "$avp(i:705)") {  // Check URI stored in $avp
(i:705)
        t_relay();
};
...
