    /// Overview of Generic Font Family Names
    /// =====================================
    /// Some media formats allow the specification of font family names to be used to style text they carry. Sometimes, an
    /// external specification (e.g., CSS) may be used to style the text carried by the media format. In either case, the
    /// specification may be concrete, indicating an installed platform font (e.g., "Times New Roman", Helvetica). It may be
    /// abstract, indicating a category of font to use (e.g., serif, sans-serif). This abstract designation is often termed
    /// a "generic font family".
    ///
    /// CSS for example allows a 'font-family' property specification such as this:
    ///
    /// font-family: Helvetica, sans-serif;
    ///
    /// This uses both the concrete family name "Helvetica" and the generic family name "sans-serif".
    ///
    /// Generic font families may be common across media formats (e.g., both CSS and 3GPP timed text allow "sans-serif" and "serif").
    /// Other formats may have generic font identifiers that do not align exactly (e.g., TTML allows "monospaceSerif and "monospaceSansSerif" in
    /// addition to "monospace"). Some formats might not carry names but have numeric values mapping to a generic font identifier.
    /// Simply put, different formats use different ways to express their generic fonts.
    ///
    /// The use of generic font families is also important for media accessibility. The Media Accessibility framework can map eight categories
    /// of abstract fonts to an installed font. Users may choose to override each of these categories to a different installed font. This
    /// remapping should work if the content or external styling indicates a generic font. It should not however try to remap a concrete font like "Helvetica".
    /// Consequently, it is important to distinguish between the generic and concrete fonts expressed by the author.
    ///
    /// To accommodate what is expressible in media formats and to support media accessibility overrides, generic font families can be
    /// specified with the kCMTextMarkupAttribute_GenericFontFamilyName attribute which carries the identifier for one of the various
    /// generic font specification forms supported across media formats. These generic font identifiers are the kCMTextMarkupGenericFontName_*
    /// prefixed constants also defined here. New identifers may be added in the future.
    ///
    /// Concrete fonts are specified using the kCMTextMarkupAttribute_FontFamilyName attribute also defined in this header.
