Dear John, Peter, all,

Following up on the discussion below, in order to address the concerns you brought up earlier:

If we believe that the "Unicode standard for joining-script shaping" does not accurately describe to essence of the document [20] referenced in the Bibliography - we need to come up with a new [improved] descriptive name to be used both for the Bibliography reference (essentially, a new name for the link to the ArabicShaping.txt published by Unicode) and to be used in the text of the feature descriptions that reference that document.

We need to finalize and review ballot comment that are due to be submitted by Sep. 15.

Thank you,

Strictly speaking, this wasn't the reason. Using explicit links as references in the text of the ISO standard is against ISO directives but since the document has the Bibliography section all links should go there. The reference [20] was added and it explicitly points to the ArabicShaping.txt but in order to include it in the text and in the Bibliography section we needed to give this reference a descriptive name, something that we can use in both the feature description and as a Bibliography entry. You proposed "Unicode standard for joining-script shaping" as its name and that was it. Since both the descriptive text and the new Bibliography entry are part of the same DAM2 document we can easily change it to any other descriptive name that you think would work best.

Thank you,
