-- The t'GI.Pango.Structs.Attribute.Attribute' 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/@].
