Opt Subject: UAX #44 feedback
The following sentence in the fourth column of Table 9 (Property Table) for the Unified_Ideograph property should be removed: "The Unified_Ideograph property is used in the definition of Ideographic Description Sequences." A similarly-worded sentence, changing Unified_Ideograph to Ideographic, should be appended to the fourth column of the Ideographic property. See Section 18.2, subsection Ideographic Description Sequences, for the justification.
Feedback above this line was reviewed prior to UTC #150.

Opt Subject: PRI #329: Soft_Dotted is defined vaguely
Soft_Dotted is assigned to “Characters with a "soft dot", like i or j. An accent placed on these characters causes the dot to disappear. An explicit dot above can be added where required, such as in Lithuanian.” This is vague. What is an accent? What does “placed on” mean? What counts as a dot above? I think the intent is for the dot to disappear when the character is the base of a grapheme cluster which has a ccc=230 character, and for the explicit dot above to be U+0307 COMBINING DOT ABOVE. However, one might argue that U+2DE3 COMBINING CYRILLIC LETTER DE is not an accent so it doesn’t remove the dot, or that you never really want to remove the dot before U+20E7 COMBINING ANNUITY SYMBOL so it doesn’t remove the dot, or that U+031A COMBINING LEFT ANGLE ABOVE (ccc=232) is “placed on” its base so it does remove the dot, or that it is silly to remove the dot of a Latin letter before a non-Latin mark like U+0F83 TIBETAN SIGN SNA LDAN, or that U+11101 CHAKMA SIGN ANUSVARA should be used for Lithuanian. So this property needs to be more clearly defined.

Opt Subject: PRI 329 Proposed Update UAX #44, UCD
I noticed some items in #44 that I'd like to see fixed. 1. http://www.unicode.org/reports/tr44/proposed.html#Obsolete_Properties This section should have a table like in http://unicode.org/reports/tr44/proposed.html#Deprecated_Properties and http://unicode.org/reports/tr44/proposed.html#Stabilized_Properties, that *lists all and only* the obsolete properties. 2. http://unicode.org/reports/tr44/proposed.html#Property_Index_Table The Obsolete, Deprecated, and Stabilized properties should also be consistently marked in this table. For example, ISO_Comment is not so marked. 3. http://unicode.org/reports/tr44/proposed.html#Contributory_Properties These should also have a table, or point to #Property_Index_Table. In addition, the note from 5.13 (repeated below) needs to be repeated at the end of the Contributory_Properties section, so that people see the list of properties that behave like Contributory properties even though they aren't: A subset of Unicode normalization-related properties are not recommended for public APIs. See Section 5.7.5, Decompositions and Normalization. BTW, I think in practice it is not at all worth trying to make a distinction between Obsolete, Deprecated, and Stabilized — people really shouldn't be using any of them! — but that is another matter.
