ICU4J Proposal: Addition of new APIs in RuleBasedCollator and CollationElementIterator

Proposal to add APIs in com.ibm.icu.text.RuleBasedCollator and 
com.ibm.icu.text.CollationElementIterator to publicly accept 
com.ibm.icu.text.UCharacterIterator arguments.

Please respond with comments by Oct 22nd 2003.

This proposal is with respect to jitterbug 2212, 
http://www.jtcsv.com/cgibin/icu-bugs/collation?id=2212.

API to be added to com.ibm.icu.text.RuleBasedCollator
/**
     * Return a CollationElementIterator for the given UCharacterIterator.
     * The source iterator's integrity will be preserved since a new copy
     * will be created for use.
     * @see CollationElementIterator
     */
    public CollationElementIterator 
getCollationElementIterator(UCharacterIterator source)

API to be added to com.ibm.icu.text.CollationElementIterator

/**
     * <p>Set a new source string iterator for iteration, and reset the
     * offset to the beginning of the text.
     * The source iterator's integrity will be preserved since a new copy
     * will be created for use.
     * </p>
     * @param source the new source string iterator for iteration.
