Stephen J Day	3150937b9f	reference: refactor grammar and regular expressions ... To resolve some inconsistencies between the grammar and the regular expressions, the grammar has been slightly refactored to match the intent. The regular expressions have been redefined with the same structure to make it easier to verify the grammar is correct.
