2014-02-07 -- Changed shell_entity to have an explicit subordinate
attribute for use with open shell.
2013-10-16 -- Changed line_entity to have an explicit form attribute
to support form 1 and 2 of entity 110. Added a new element
construction_geometry to the use_flag enum.
2011-09-11 -- Changed shell_entity to have an explicit form attribute
to support form 1 and 2 of entity 514.
