# Declarations for type attributes.
|
|
#
|
|
|
|
# A type attribute can be used to identify a set of types with a similar
|
|
# property. Each type can have any number of attributes, and each
|
|
# attribute can be associated with any number of types. Attributes are
|
|
# explicitly declared here, and can then be associated with particular
|
|
# types in type declarations. Attribute names can then be used throughout
|
|
# the configuration to express the set of types that are associated with
|
|
# the attribute. Except for the MLS attributes, attributes have no implicit
|
|
# meaning to SELinux. The meaning of all other attributes are completely
|
|
# defined through their usage within the configuration, but should be
|
|
# documented here as comments preceding the attribute declaration.
