Bug in RFC3261: Proxy-Require not allowed in ACK

Table 2 in RFC3261 disallows Proxy-Require in ACK requests (i.e. it has a '-'). Some standards (e.g. RFC3323, RFC3329) seem to rely on the ability to include a Proxy-Require in an ACK to a 2xx response, although they are not very explicit on this.
 
RFC3261 explicitly says that Proxy-Require MUST NOT be used for CANCEL or ACK to non-2xx (which are hop by hop), but I believe the intention was to allow it for ACK to 2xx. Therefore, table 2 should say 'o' here
