Patch from Galen Charlton:

[This] patch adds a new XSL transform for indexing purpose that converts MARC21 880 fields (which are used for alternate graphic representations, i.e., vernacular representations of foreign language strings) to the base tags.

For example, if a MARC record for a Chinese book has

245.00 $6 880-01 $a Ba shi san nian duan pian xiao shuo xuan
880.00 $6 245-01/$1 $a\u516b\u5341\u4e09\u5e74\u77ed\u7bc7\u5c0f\u8aaa\u9078

this stylesheet will transform it to the equivalent of

245.00 $6 880-01 $a Ba shi san nian duan pian xiao shuo xuan
245.00 $6 245-01/$1 $a\u516b\u5341\u4e09\u5e74\u77ed\u7bc7\u5c0f\u8aaa\u9078

This allows an indexing XPath like //marc:datafield[@tag='245']/marc:subfield[@code='a'] to bring in both the vernacular and transliterated versions of the 245$a.

[ED: pretend the \u-encoded unicode are real characters ... curse you, Chrome, for not giving me the raw string!]
