RFC 1034 The domain system provides such a feature using the canonical name (CNAME) RR. A CNAME RR identifies its owner name as an alias, and specifies the corresponding canonical name in the RDATA section of the RR. If a CNAME RR is present at a node, no other data should be present; this ensures that the data for a canonical name and its aliases cannot be different. This rule also insures that a cached CNAME can be used without checking with an authoritative server for other RR types.
Now go complain to the WC3 for not adding support for SRV to the protocol or for defining a RR which points to a HTTP(S) server like MX points to a server for SMTP.
