This appendix is informative, not normative.

This appendix summarizes the changes that have been made since the SVG 1.1 Second Edition Recommendation.

N.1. Editorial changes

A number of stylistic changes have been made to the specification to make it more readable. These include the following:

• A change towards using styling similar to contemporary CSS specifications.
• Annotations have been added to the specification to reflect features that the Working Group has resolved on including and for which a member of the group has committed to drive that feature.
