This page tracks some of the specification issues we've encountered more recently while implementing SVG.
Ideally issues should be tracked using issue tracking software, but that's often less accessible to "outsiders", and it can take time and many iterations to hash out a good clear description for an issue. In that respect, wiki pages (with their version history and the ability to revert changes) are very useful.


When we discovered issues with the SVG specification in the past, we used to report them to the SVG working group via www-svg@w3.org in the belief that they would be tracked and (eventually) fixed. However, it has since come to light that many of the issues that are reported to www-svg never make it into their tracking system, and of those that do, many are eventually simply closed (unresolved) because nobody in the working group picks them up. It is still worth keeping a record of the issues we encounter, but just sending them into the black hole that is www-svg would be a bad idea. Hence this page.

Ideally issues should be tracked using issue tracking software, but that's often less accessible to "outsiders", and it can take time and many iterations to hash out a good clear description for an issue. In that respect, wiki pages (with their version history and the ability to revert changes) are very useful.
