||Transcluded by Sword of Moonlight Extension Library / list of extensions.|
Extensions in this section take the form of custom #numbers which can then be used to assign values to extensions that accept "numbers". Often these extensions will end with _factor or _multiplier. If their numbers accept input parameters they end with _quantifier. An extension that ends with _identifier accepts a positive whole 24bit number or a packed series of numbers setup with id. Such extensions may or may not accept input parameters.
The name of an extension in this section is limited to a 30 character name, a subscript in the range of [0-65534], and a 30 character label, all separated by a single underscore (_). A name is required. If the subscript is unspecified then 0 is assumed. Labels cannot include equal signs (=) and cannot be applied when the subscript is omitted, as the subscript separates the name from the label.
A trailing underscore (_) is interpreted as an incomplete label. The value to the right of the equal sign (=) is taken to be the label. Just the same a number can be specified without being assigned to. Doing so will simply apply a label. It is not necessary to declare numbers in advance. Therefore applying labels is the only reason to omit the assignment. Numbers are not assigned in any particular order accept where _$ appears.
All-lowercase names for numbers are reserved. Both for the numbers of SomEx / list of numbers and future extensions of the #Number section. This does not mean you cannot use such names, however you should think twice before doing so. Furthermore all symbolic Unicode character codes are reserved. In other words, the names of custom numbers should be limited to Unicode script only. These restrictions do not apply to labels. However labels are advised to avoid the = and  characters, however [ and ] can be used if matched and in that order.
Note: that it would be ideal if where multiple Ex.ini files are in use assignment is encapsulated, or occurs before moving onto the next file by default. However this behavior has not yet been put into effect as of 220.127.116.11.
