/* 
 * Dictionary definitions for objects specified for DCCA by 3GPP.
 *
 * This extensions contains a lot of AVPs from various 3GPP standards
 * documents, and some rules for the grouped AVPs described therein.
 *
 * This extension does not contain ALL AVPs described by 3GPP, but
 * quite a big number of them.
 *
 * When extending the AVPs, please edit dict_rx.org instead and
 * create pastable code with contrib/tools/org_to_fd.pl.
 *
 * Some points of consideration:
 * 1. This dictionary could be split up per document.
 *
 * + pro: you can only load the AVPs/Rules you're interested in ->
 * smaller memory size
 *
 * - con: the documents use AVPs from each other A LOT, so setting the
 * dependencies correctly will be annoying
 *
 * - con: you need to load all of them as extensions
 *
 * 2. This dictionary contains ONE AVP in the "3GPP2" vendor space,
 * since I found it wasteful to write a separate dictionary just for
 * one AVP. Also, it is defined in a 3GPP document.
 *
 * 3. While there are quite a number of rules here already, many more
 * are missing. I've only added rules for those grouped AVPs or
 * commands in which I was concretely interested so far; many more
 * will need to be added to make this complete.
 *
 * That being said, I hope this will be useful for you.
 *
 */


/*
 * Some comments on the 3GPP Standards documents themselves:
 *
 * 1. It would be good if 29.061 was reviewed to check for each AVP if
 * it is Mandatory or not. The data currently in the document does not
 * match what was in the previous version of the freeDiameter
 * extension (the one that existedbefore I rewrote it) or what I saw
 * so far. IIRC, even the table and the document contradict each
 * other. The AVP table is also missing an entry for
 * "External-Identifier", 28.
 *
 * 2. 29.140 has conflicting AVP names with other documents:
 *   - Sequence-Number is also in 32.329
 *   - Recipient-Address is also in 32.299
 *   - Status is also in 32.299
 *
 * 3. 29.229 has name conflict with 29.329 about User-Data (different
 * AVP code 702, instead of 606) -- the weird thing is, the latter
 * uses some AVPs from the former, but not this one.
