data/ directory README
Layout
------
Each directory
- must contain exactly one EXPRESS schema
-- this schema must be useful to end users - i.e. not a schema crafted to test SCL
- must be named after the numeric designation of the schema *if and only if*
it is an IS STEP schema
-- examples: ap214e3, AP235, etc (case insensitive)
-- directories for schemas that are not STEP IS must be named differently
- may contain part 21 files
-- these files must be compatible with the schema
