Some maing characters required for Catalan are missing:
"-" (hyphen) is a mandatory character in some Catalan words like: "gara-gara" or "baliga-balaga". Note that "baliga-balaga" isn't a compound word, as "baliga" "balaga" aren't valids Catalan words, but "baliga-balaga" is it.
"·" (U+00B7) is a used to type words like "goril·la" and "paral·lel".
"ŀ" (U+0140), currently in main characters, can be placed as auxiliar character. "l·" encoding is preferred by Unicode. Also, standard Spanish PC keyboard layout (the one used by Catalan users) lacks "ŀ" support. So "ŀ" is not frequently used to type in Catalan.

Change DAIP to convert composed to separate l and dot, move composed to aux exemplars, hyphen should just be in punct, fix up any problems in 24 dres post-processing.
1. - 002D is punctuation and must be in the punctuation exemplars, but there were no punctuation exemplars, so I added the set from "es" as a reasonable start (since it includes the ¡ ¿ also needed in Catalan, and also includes 002D).
2. · 00B7 is also punctuation but is allowed to be in the main exemplars because it has WordBreak property MidLetter (see http://www.unicode.org/reports/tr35/tr35-general.html#Character_Elements), so added it in the main exemplars.
3. ŀ 0140 was moved from main to aux exemplars.
4. Updated DAIP to transform 013F -> 004C 00B7, 0140 -> 006C 00B7 in "ca" and its sublocales for non-exemplar values.
