20                        <xsd:documentation>The The power loss for one way travel of a beam of light, usually measured
21                        in decibels per unit length. It is necessary to include both the value (and its unit) and the
22                        wavelength. The wavelength varies with the refractive index, while the frequency remains constant.
23                        The wavelength given to specify this type is the wavelength in a vacuum (refractive index = 1).</xsd:documentation>
