1. The NAICS Code System that's listed really should indicate which year, i.e., 2007. Note that it's not in a value set table anywhere—could be included because it's referenced as a source of some of the codes in participation-role-type and security-role-type, otherwise I can't tell why it's even included. Also, should Symbolic Name be PHIN VADS or Table 0396?

2. The SIC Code System description should state that it's ONLY be used for backwards compatibility because it's very outdated and no longer used by the federal government. Note that it's not in a value set table anywhere.

3. The SOC Code System should indicate year, i.e., 2000. Note that it's not in a value set table anywhere—could be included because it's referenced as a source of some of the codes in participation-role-type and security-role-type, otherwise I can't tell why it's even included. Also, should Symbolic Name be PHIN VADS or Table 0396?
