[2.1.3]

- Buggy treatment of end tags of elements that have required attributes fixed (does not manifest on default tag-set)
- Spurious internal content reorganization error suppressed
. Error unit tests can now specify the expectation of no errors. Future iterations of the harness will be extremely strict about what errors are allowed
