The StringWithQualityHeaderValue class provides support for strings with a quality factor used in some headers as defined in RFC 2616 by the IETF.

Quality factors allow the user agent to indicate the relative degree of preference for various options in various headers including the Accept, Accept-Charset, Accept-Encoding, and Accept-Language headers. Quality uses a scale from 0 to 1. The default value is q=1.
