<xs:annotation>
<xs:documentation>The letter-spacing attribute specifies text tracking. Values are either "normal" or a number representing the number of ems to add between each letter. The number may be negative in order to subtract space. The default is normal, which allows flexibility of letter-spacing for purposes of text justification.</xs:documentation>
