Jonathan Cranford reported two issues in the spec: 1. Pages 11-12 of the draft include a sample DFDL schema for a comma-separated format. I asked you about this example before, and you told me that there's no ambiguity between having a comma (,) as a separator and as the textStandardGroupingSeparator. I think I understand why (there's a question on that below). Regardless of why, though, I think that having the same character as both the separator and textStandardGroupingSeparator is a potential point of confusion, especially this early in the document. So I recommend reworking the example to avoid the appearance of ambiguity and avoid relying on the technical workings of textNumberPattern, which hasn’t been introduced yet. Is this example not ambiguous because none of the textNumberPattern attributes contain a grouping separator? If so, couldn’t the textStandardGroupingSeparator attribute just be removed from the example so that others don't get confused on it like I did? 2. Minor editorial comment - Page 15 – I think 3rd bullet should end in period instead of a comma, for consistency with other bullets.
