This header file contains definitions of constants used with accessibility objects that represent attributed strings. An attributed string is an association of a range of characters and their attributes, such as color and font. If an accessibility object represents an attributed string, the value of its kAXParameterizedAttributeStringAttribute attribute is an attributed string object (a CFAttributedStringRef or an NSAttributedString) that uses the constants defined in this header file to define its attributes.
