-{.glossary}
-
-common attributes
-: Every rule has a set of common attributes. See Bazel's
-  [Common attributes](https://bazel.build/reference/be/common-definitions#common-attributes)
-  for a complete listing
-
-rule callable
-: A function that behaves like a rule. This includes, but is not is not
-  limited to:
-  * Accepts a `name` arg and other {term}`common attributes`.
-  * Has no return value (i.e. returns `None`).
-  * Creates at least a target named `name`
-
-  There is usually an implicit interface about what attributes and values are
-  accepted; refer to the respective API accepting this type.
-
-simple label
-: A `str` or `Label` object but not a _direct_ `select` object. These usually
-  mean a string manipulation is occuring, which can't be done on `select`
-  objects. Such attributes are usually still configurable if an alias is used,
-  and a reference to the alias is passed instead.
-
-nonconfigurable
-: A nonconfigurable value cannot use `select`. See Bazel's
-  [configurable attributes](https://bazel.build/reference/be/common-definitions#configurable-attributes) documentation.
