Discussion
Custom attributes are glyph attributes such as NSGlyphInscription or attributes defined by subclasses. Subclasses that define their own custom attributes must override this method and provide their own storage for the attribute values. Nonnegative tags are reserved; you can define your own attributes with negative tags and set values using this method.
