Conform to ISO standards

Couldn't find any other standard sites. This sort of thing might be useful - even better, if we can get an open source project going. Do you know of any, @btford?

Start by reviewing the linked ISO catalogue entry and the write-good project description to determine which standard and prose rules are intended. The issue names no files or tests, so first establish the target standard and concrete acceptance criteria before identifying the implementation and validation work.
