-# === PermitScrubber
-#
-# PermitScrubber allows you to permit only your own tags and/or attributes.
-#
-# PermitScrubber can be subclassed to determine:
-# - When a node should be skipped via +skip_node?+
-# - When a node is allowed via +allowed_node?+
-# - When an attribute should be scrubbed via +scrub_attribute?+
-#
-# Subclasses don't need to worry if tags or attributes are set or not.
-# If tags or attributes are not set, Loofah's behavior will be used.
-# If you override +allowed_node?+ and no tags are set, it will not be called.
-# Instead Loofahs behavior will be used.
-# Likewise for +scrub_attribute?+ and attributes respectively.
-#
-# Text and CDATA nodes are skipped by default.
-# Unallowed elements will be stripped, i.e. element is removed but its subtree kept.
-# Supplied tags and attributes should be Enumerables
-#
-# +tags=+
-# If set, elements excluded will be stripped.
-# If not, elements are stripped based on Loofahs +HTML5::Scrub.allowed_element?+
-#
-# +attributes=+
-# If set, attributes excluded will be removed.
-# If not, attributes are removed based on Loofahs +HTML5::Scrub.scrub_attributes+

-# === TargetScrubber
-#
-# Where PermitScrubber picks out tags and attributes to permit in
-# sanitization, TargetScrubber targets them for removal
-#
-# The open architecture of PermitScrubber is used to redefine:
-# - +allowed_node?+
-#   # allowed if node is not in tags
-# - +scrub_attribute?+
-#   # should scrub if attribute name is not in attributes
-#
-# +tags=+
-# If set, elements included will be stripped.
-#
-# +attributes=+
-# If set, attributes included will be removed.
