PDS3 to PDS4 label transformations: Capitalize the first letter of each word in the value instead of all lowercase.

From Daniel Politte and Susie Slavney:

Minor quibble: Keyword values in the PDS3 label are in all uppercase, and are transmitted to the PDS4 label in all lowercase.
Examples:
   " <Observing_System>
        <Observing_System_Component>
            <name>mars science laboratory</name>
            <type>Spacecraft</type>
        </Observing_System_Component>
      <Observing_System_Component>
           <name>sample analysis at mars</name>
            <type>Instrument</type>
      </Observing_System_Component>
    </Observing_System>
    <Target_Identification>
         <name>mars</name>
         <type>Planet</type>
    </Target_Identification>"
We would prefer these values to be transmitted with the first letter of each word capitalized, e.g. Mars Science Laboratory, Sample Analysis at Mars, and Mars (planet name).
