code (1.8 MB (i18n) + 1.3MB (common)):

• code components:
• i18n: coll, format, regex, translit
• common: conv, prop (hardcoded), str, breakiter, set
• separate library targets for separate functionality
• top level target which depends on all other targets
• restructure code to remove dependencies: break away builder from runtime code
• e.g. code for collator includes build and runtime
• e.g. use reflection instead of builder / dependencies
• same applies to unicodeset, breakiterator
• split not just functionality, but also by frequency of use. (thus builders, and other code that isn't used very often)

data (13 MB):

• monolithic 11mb data file -> break up into pieces
• format, conv, coll, tz
