+Regression test "canonxml":
+----------------------------------------------------------------------
+
+- An XML file is parsed, and the contents are printed in a canonical
+ format.
+
+- The output is compared with a reference file. The test is only
+ passed if the output and the reference are equal.
+
+- Test data "data_jclark_valid":
+ Contains the samples by James Clark that are valid. The subdirectories:
+ - sa: standalone documents
+ - not-sa: non-standalone document (with external DTD)
+ - ext-sa: non-standalone document (with other external entity)
+
+ Tests that are not passed have been moved into the *-problems directories.
+ The reason is typically that characters have been used not in the
+ Latin 1 character set.
