-# This file describes all Blink IDL extended attributes and allowed values.
-# If any IDL file uses an extended attribute or values not listed below, the
-# build will fail.
-# If you would like to add a new extended attribute or value, please:
-#     (1) add the extended attribute or value to this file
-#     (2) add an explanation to the Blink IDL extended attributes document:
-#         http://www.chromium.org/blink/webidl/blink-idl-extended-attributes
-#     (3) add appropriate test cases to run-bindings-tests
-#
-# The syntax of this file is as follows:
-#     - One extended attribute per one line: Name and (optionally) Values.
-#     - "Attr" means that the Attr does not take a value, i.e. [Attr].
-#     - "Attr=X" means that Attr takes a required value, which must be X;
-#       i.e. [Attr=X].
-#     - "Attr=X|Y|Z" means that Attr takes a required value, and the valid
-#       values are X, Y, and Z, and combinations thereof;
-#       e.g. [Attr=X], [Attr=Y], [Attr=X|Z].
-#       The separator must be | or &, so [Attr=X&Z] is also valid; the
-#       separator makes a difference for Conditional, but otherwise is simply
-#       a style convention.
-#     - "Attr=|X|Y|Z" means that Attr takes an optional value, whose valid
-#       values (if present) are X, Y, and Z, and combinations thereof; e.g.
-#       [Attr], [Attr=X], [Attr=Y], [Attr=X|Z], [Attr=X|Y|Z], [Attr=X&Z].
-#       Note that including an empty value in the list, as in [Attr=X||Y],
-#       is NOT valid: the value is optional, but empty values are not allowed.
-#     - "Attr=*" means that Attr takes a required value, which can be
-#       arbitrary, and combinations thereof, e.g. [Attr=IndexedDB],
-#       [Attr=DeleteFunction], [Attr=X|Y].
-#     - "Attr=|*" means that Attr takes an optional value, which can be
-#       arbitrary, e.g. [Attr], [Attr=X].
-#     - "Attr=X|*" means that Attr takes an required value, which can be
-#       arbitrary, but that "X" is standard, e.g. [Attr=X], [Attr=Foo].
