Field Notes


DT_component_index_ptr

 Used only to describe an element within a <Data Table>.

 Array of indices into other <Data Tables>, where each indexed
 <Data Table> is one of the ordered <Data Table> components of
 the current <Data Table>. (The index is used to identify the
 target <Data Table> within the ordered list of component
 <Data Tables>.)

DT_library_index_ptr

 Used only to describe an element within a <Data Table>.

 Array of indices into other <Data Tables>, where each indexed
 <Data Table> is one of the <Data Tables> in the <Data Table
 Library>.  The index is used to identify the target <Data Table>
 within the <Data Table Library>.

ee_code_ptr

 an array of EDCS Enumerant Codes.

em_code_ptr

 an array of EDCS Metadata Codes.
