 * Associations XML files must match the following DTD:
 * <pre>
 * <!ELEMENT associations (association*)>
 * 
 * <!ELEMENT association (filename?,symlink?,hidden?,readable?,writable?,executable?)>
 * <!ATTLIST association command CDATA #REQUIRED>
 *
 * <!ELEMENT filename EMPTY>
 * <!ATTLIST filename value CDATA                 #REQUIRED>
 * <!ATTLIST filename case_sensitive (true|false) #IMPLIED>
 *
 * <!ELEMENT symlink EMPTY>
 * <!ATTLIST symlink value (true|false) #REQUIRED>
 *
 * <!ELEMENT hidden EMPTY>
 * <!ATTLIST hidden value (true|false) #REQUIRED>
 *
 * <!ELEMENT readable EMPTY>
 * <!ATTLIST readable value (true|false) #REQUIRED>
 *
 * <!ELEMENT writable EMPTY>
