Sorry, I may not have emphasized this enough, but in the grammar, I wrote:
- A KEY optionally begins with `-', and obligatorily contains `@' or
`&' followed by a string of characters which begins with a letter
or `_', and may contain alphanumeric characters and the following
*internal* punctuation characters:
:.#$%&-+?<>~/
The `internal' here was meant to express exactly what Aaron said: keys
can contain punctuation, but may not end (or begin) with punctuation.
Best,
