DFDL expression changes:
- support added for dfdl:contentLength(), dfdl:valueLength(), fn:error(), and math:pow() functions
- support equality comparisons of xs:hexBinary types
- fix bugs with integer equality comparisons and converting differing integer types
- fix bugs with div/idiv not using the appropriate kindof division
- fix bugs with daf:trace on complex types
creation of a new data input/output stream layer
add support for 3-, 4-, 5-, 6-, and 7-bit ASCII encodings
add property daf:parseUnparsePolicy and tunable to enable only parsing, unparsing, or both
add tunable unqualifiedPathStepProperty to specify how unqualified DFDL expression path steps are resolved

support for xs:hexBinary type with bit lengths
support for xs:ignoreCase="yes"
support for xs:union restrictions
support for runtime valued properties
improved diagnostic messages
numerous bug fixes and performance improvements
fix failure to import/include schemas with deep paths. includes and imports now reliably import files in jars or relative to paths on the classpath

API

new parse and unparse API with InfosetInputter's and InfosetOutputter's
native infoset support for JDOM, w3c DOM, Scala XML Nodes, XML Text, and JSON
calling isError on a ParseResult now returns true if either there were parse errors OR validation errors
add new methods (isProcessingError and isValidationError) to ParseResult to determine if isError was true due to a parse error or a validation error
deprecated the canProceed() method, instead one should use !isError()

TDML

support for setting tunables in tdml:defineConfig
created an XSL stylesheet for creating DFDL tutorials from TDML files
