This file provides a relitvely simple xslt transformation on 800-54v4 800-53-controls.xml file
to generate a set of json files representing the controls.

usage: $> xsltproc - -stringparam paramname paramvalue control2json.xsl 800-53-controls.xml
example: $>  xsltproc - -stringparam controlnumber AT-3 lib/control2json.xsl data/800-53-controls.xml

namespace notes: 
    It is necessary to explicitly define and use the default name space `xmlns="http://scap.nist.gov/schema/sp800-53/2.0"` 
    in the xsl file that is defined in the 800-53-controls file.
