Validation tools for test suite

[rmraya]

The tools I use for checking the XLIFF files in the test suite are:

• XLIFF Manager (based on OpenXLIFF Filters)
• XLIFFValidation (uses OpenXLIFF Filters and XLIFF Schematron)

Source code for all tools is on GitHub and you can inspect how validation is performed.

Note that OpenXLIFF Filters uses Java to validate Core, Metadata, Matches and Glossary modules. All other modules are not checked.
