Future versions of this document may introduce even more optional parameters for the areafix URLs, encouraging somewhat tighter control over rescan parameters, packer/unpacker settings and formats, etc.
Programs interpreting areafix URLs SHOULD NOT be sure whether it is safe to ignore any of the unknown parameters. Some of future extensions may dramatically change the URL's meaning, as "unsubscribe" is already able to change it to the opposite.
If an unknown parameter is encountered in the areafix URL, the user SHOULD always be asked whether it can be discarded safely enough.
If an areafix URL is published in the same echomail area that is involved in the designated action, then the <echomail-area-name> MAY be omitted.
Examples:
...if you don't like this area, areafix:?unsubscribe>https://fido.g0x.ru/?areafix:?unsubscribe>areafix:?unsubscribe from it!
...if you feel that some echomail messages is missing, then your current uplink is not reliable. You'd better subscribe using areafix:?uplink=2:5063/88>https://fido.g0x.ru/?areafix:?uplink=2:5063/88>areafix:?uplink=2:5063/88
If such a relative "areafix:" URL is encountered outside of Fido echomail, then the URL is not valid.
6.3. "echomail:" scheme -+---------------------
Echomail is an important and powerful force in Fidonet. Echomail is, by definition, a broadcast medium. See echomail specifications in FTS-0004.
An echomail area is a shared base of messages that have common areatag (area identifier) and are distributed through Fidonet via hierarchical and/or p2p-alike connections between individual Fidonet systems (nodes and points).
The "echomail:" scheme is used to designate a Fidonet echomail area as a location where echomail can be sent to.
The character "/" has its literal meaning for this scheme.
The "to" optional parameter is used to designate the name of echomail addressee. Its default value SHOULD be "All", meaning all of the area audience. The default value MAY also be given by some user setting of the echomail composer used to process the "echomail:" URL.
The "subject" optional parameter is used to designate the subject line of the echomail message composed. Its default value is empty; the default value MAY also be determined by some user setting of the echomail composer used to process the "echomail:" URL.
The "subj" optional parameter is used as a shorter equivalent to the "subject" parameter. If the optional parameter "subject" is not present in a given URL, the value of "subj" parameter MUST be taken instead the value of "subject", provided that "subj" is present.
The "from" optional parameter is used to designate the name of the echomail letter's author. Its default value is usually defined within the echomail composer settings.
The "body" optional parameter is used to designate the body part of the echomail message composed. (Its default value is empty.) The echomail composer MAY wrap the value of "body" parameter in elements of some user-defined message template (user-defined signature, greeting, etc.)
The URL schemes enumerated below designate named objects that can be accessed, read, browsed, etc.
According to the above section of delimiter guidelines, the "://" character triplet (and not the ":" character) SHOULD be used as the delimiter after <scheme> part of such URLs.
