Yes, but if you consider square brackets to represent grouping, then the
examples in the draft do not match the grammar, `voice-family: male 2`
for instance is not valid because <age> is not optional but omitted in
the example. However, it would match if you read (some of the) square
brackets to represent optionality. I do agree that the Working Group
does not seem to have addressed my comment yet.
