+ - Change the XCQL output to include the nasty (but official)
+ <leftOperand> and <rightOperand> wrapper elements.
+ - Change the XCQL output to use the nasty (but official)
+ rendition of prefix-mapping: a <prefixes> element,
+ containing one of more <prefix>es may appear at the top
+ of either a <searchClause> or a <triple>.
+ - Include test/regression/xmlpp.pl in the distribution: this
+ may now be used for testing whether a CQL compiler produces
+ _equivalent_ XCQL to what's in the regression test, rather
+ than requiring byte-identical output.
+ - Include the reference XCQL output in the distribution, for
+ the regression test suite to run against.
