The unparsed file does not match (HEX or md5 comparison) the source test file, kirkuk_dwellSeg_1.4607, used in the parse tests. The HEX comparison is shown below. The left is the source file. Same result whether unparsing the original or newly created infoset.

Note, the unparsed results of the other small 4607 files match the associated source file with md5 hash and HEX comparisons.
