Subject: Review of Tamil LGR dated Dec 6, 2018

We have reviewed the updated proposal dated 2018-12-06 including XML and TXT files.

Here are our findings:

TECHNICAL / DOCUMENTATION ISSUE
Tamil is one of the few LGRs that assign an "allocatable" variant, yet the LGR did not defined a "no-mix" rule to prevent needless multiplication of variant labels where the same label alternates the variant used.

The LGR makes the two encodings of SRI/SHRI allocatable but it is not clear why it would be essential, or even desirable to support all 4 permutations in a case where SHRI/SRI occurs twice in the same label.

--- SRI ---- SRI ---
--- SRI ---- SHRI ---
--- SHRI ---- SRI ---
--- SHRI ---- SHRI ---

Here "---" stands for some code points common to both labels.

It seems only necessary to allow one or the other spelling consistently for a single label.

If, unexpectedly, there is some requirement to cater to all possible permutations, then this needs to be documented very clearly and the cost for supporting it (potentially many more than 2 allocatable labels) must be spelled out.

Alternatively, the LGR should be amended to contain a "no-mix" rule, patterned after the Arabic LGR's no-mix rules, or other suitable restriction.

DOCx:
The main document shows no changes other than what looks like minor copy editing/editorial. No additional issues identified.
In section 5.2.1, only the variant sequences for 6.1.3 have been listed, but not the ones for 6.1.1 (U+0B92 U+0BB3) and 6.1.2 (U+0BC6 U+0BB3). This is not consistent and is at odd with the XML/HTML where obviously sequences appear along single code points.
The remedy is add these 2 sequences in section in 5.2.1 with references to 6.1.1 and 6.1.2 as it has already been done for the other pair.

While the two sets are slightly different because the sets for 6.1.1 and 6.1.2 are 2 to 1 variants unlike the one in 6.1.3, the difference appears immaterial for this purpose and having a full list of sequences in section 5 makes sense.

XML:
No changes found other than Date. One common editorial issue:

(1) as with all LGRs the placeholders in the <description> need to be updated with final date and URL:
       Neo-Brahmi Generation Panel, "Proposal for a Tamil Script Root Zone Label Generation Rule-Set (LGR)", [URL and Date TBD]

The XML passes the tool

TXT:
Test label file verified; existing TLDs show as valid.
