-- The @PangoAttribute@ structure represents the common portions of all
-- attributes.
-- 
-- Particular types of attributes include this structure as their initial
-- portion. The common portion of the attribute holds the range to which
-- the value in the type-specific part of the attribute applies and should
-- be initialized using 'GI.Pango.Structs.Attribute.attributeInit'. By default, an attribute
-- will have an all-inclusive range of [0,@/G_MAXUINT/@].
