Description of Issue:

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.
• Reorganization and rewrite of the Hangul Collation section.
• A new section on fourth-level weight assignments.
• A new appendix on synchronization of UCA with ISO/IEC 14651.
• Documentation of the use of U+FFFF and U+FFFE in CLDR.
• Addition of examples to some tables.
• Addition of the script-reorder parameter to Table 14.
• Better documentation of the test files.
• Added subheads to Section 3.8, Stability and reference links to the UCA change management policy pages.
