Description
The inner classes of FilterMapper.java which handle parsing of >, >=, <, and <= operations coerce their arguments into numeric expressions, although the grammar should allow for any comparable expression type to appear here (and the corresponding filter operations in org.mulgara.query.filter allow for any comparable expression).

This was a problem in the SPARQL parser. The filters were doing the correct thing, but the parser was trying to create comparisons between numbers only.
Yet another indication that we need a SPARQL test suite.
