+## Notes
+
+The gist of it is I'd like to create new codes with a prefix for the infrastructure stuff.  Like this:
+
+| org | prefix | selector | Code (8) | result |
+|-----|--------|----------|----------|--------|
+| CSVD | 9 | 0 | 00000000 | fs9000000000 |
+| TCO | 9 | 1 | 00000000 | fs9100000000 |
+| OIS | 9 | 2 | 00000000 | fs9200000000 |
+| catchall | 0 | 0 | 00000000 | fs0000000000 |
+
+Ultimately we have ZERO with the all zeros code.
+
+The code can also be more finely grained for other subcategories defined by need, published, and made super clear.
+
+I don't expect enterprise systems to be here, as they are identified and and have their own funding and such.
+
+This is limited to 10 different categories of "inf", though I do not think we will need more than this.
