* Constructs a new object with the given namespace and priority.

* where the "algo" is the hashing algorithm used (e.g., "sha1" for the SHA-1
* algorithm as specified in RFC 3174) and the "hash" is the hex
* output of the algorithm applied to the binary data itself.
* @param type The value of the 'type' attribute MUST match the syntax specified in RFC 2045.
* That is, the value MUST include a top-level media type, the "/" character,
* and a subtype; in addition, it MAY include one or more optional parameters
* (e.g., the "audio/ogg" MIME type in the example shown below includes a
* "codecs" parameter as specified in RFC 4281 [14]). The "type/subtype"
* string SHOULD be registered in the IANA MIME Media Types Registry,
* but MAY be an unregistered or yet-to-be-registered value.
* @param data The binary data. It will be Base64-encoded for you.
* @param maxage A suggestion regarding how long (in seconds) to cache the data;
* the meaning matches the Max-Age attribute from RFC 2965.
