+ - All enums should generally use an explicit start number of 10000.
+   If there are multiple "categories" in the enum entries, each category
+   should be 10000 entries apart from the next one. The start of categories
+   are thus 10000, 20000, 30000, and so on.
+
+   Adding items to an enum MUST always append to a "category", never add
+   items in the middle of a category. The order of items MUST NOT be changed.
+   Any of the above would break the ABI.
+
+   The enum item 0 is special and is used as terminator in some lists, thus
+   enums should not use this for "valid" entries (and start at 10000 instead).

+ - Mark all public API functions (SRD_API) with a @since tag which indicates
+   in which release the respective function was added (e.g. "@since 0.1.0").
+
+   If the function has existed before, but its API changed later, the @since
+   tag should mention only the release when the API last changed.
+
+   Example: The srd_foo() call was added in 0.1.0, but the API changed in
+   the later 0.2.0 release. The docs should read "@since 0.2.0" in that case.
+
+   Non-public functions (static ones, and those marked SRD_PRIV) don't need
+   to have @since markers.
+
+   The @since tag should be the last one, i.e. it should come after @param,
