PRI #203 Proposed Update for UTS #10: Unicode Collation Algorithm
http://www.unicode.org/review/pri203/

This proposed update aligns with Unicode 6.1, and includes the following changes:

• A major revision to the ordering of variable characters into groups, separating punctuation and symbols. Some other characters have changed ordering as well.
• A new option for sorting, IgnoreSP, that ignores (shifts) only whitespace and punctuation (and not general symbols)
• Clarifications or fixes to text on soft-hyphen, contiguous weights, and collation grapheme clusters.
• A new section on asymmetric search.
• Review notes for new UCA verification tables, and several other areas where the text will be changed.
