+- Comment begins with `#`. It may begin anywhere in the file. The content after `#` is treated as comment and will be ignored in production.
 - Subdomain begins with `domain:`, followed by a valid domain name. The prefix `domain:` may be omitted.
 - Full domain begins with `full:`, followed by a complete and valid domain name.
 - Keyword begins with `keyword:`, followed by a substring of a valid domain name.
 - Regular expression begins with `regexp:`, followed by a valid regular expression (per Golang's standard).
 - Domain rules (including `domain`, `full`, `keyword`, and `regexp`) may have none, one or more attributes. Each attribute begins with `@` and followed by the name of the attribute. Attributes will remain available in final lists and `dlc.dat`.
-- Domain rules may have none, one or more affiliations, which additionally adds the domain rule into the affiliated target list. Each affiliation begins with `&` and followed by the name of the target list (nomatter whether the target has a dedicated file in data path). This is a method for data management, and will not remain in the final lists or `dlc.dat`.
-- Inclusion begins with `include:`, followed by the name of another valid domain list. `include:listb` in file `lista` means adding all domain rules of `listb` into `lista`. Inclusions with attributes stand for selective inclusion. `include:listb @attr1 @-attr2` means only adding those domain rules *with* `@attr1` **and** *without* `@attr2`. This is a special type for data management, and will not remain in the final lists or `dlc.dat`.
