+/**
+Specifies the mixin protocol for getting and setting character and paragraph
+format attributes.
+
+It is inherited by classes which support character and paragraph formatting,
+e.g. CRichText and CGlobalText. Its purpose is to allow developers to apply
+and retrieve formatting without needing to know which type of editable text
+is involved.
+
+All functions defined in this class use a document position and a length.
+These values are only relevant to rich text. In general, they must be valid
+(i.e. the range must not extend beyond the bounds of the document), or a panic
+occurs. In global text, formatting is applied globally, so that the length
+and position values are ignored.
