MarkUp Validation Service

December 01, 2002:

Maintenance release to fix various minor issues reported against the November 26 release. Stylesheet updates, ability to turn on Verbose output, and bug fixes.

November 26, 2002:

• Improved design of layout, including for Validation results.
• Added "beefed up" Tip-of-the-Day.
• Many accessibility fixes, both to the web site and the Result page.
• Major internal restructuring. The code has undergone significant refactoring with many benefits. It is more readable and easier to understand, much more robust, much improved security, more modular, and performance should be significantly better. There is tentative support for running under mod_perl (leading to even greater performance enhancements) and memory consumption should be much improved.
• Many new document types are supported and support for some existing document types has been improved. Notable changes and additions include:
  • Support for application/xhtml+xml.
  • Support for XHTML+MathML and XHTML+MathML+SVG.
  • Support for SVG and image/svg+xml.
  • XHTML 1.0 Second Edition and XHTML 1.1.
• Output has been reworked to be easier to understand.
• And a whole bunch of bugfixes... :-)
