The SVG specs, and now the FX specs that define elements, have a lot of repeated text about certain elements being "never directly rendered" and how this interacts with the display property. However, we do not have a centralized section defining this behavior, and we do not have any easy way to pull up a list of which elements are affected.
For both the SVG accessibility specs and the SVG 2 sections on focus management and interactivity, it would make things much simpler if we could simply refer to a category of elements that are never directly rendered or not rendered in a particular context. However, this requires a number of complementary changes to different parts of the specs, so I thought I'd warn everyone before I push changes (or make a pull request, for the FX specs). Planned changes in SVG 2: - Include a new section in the rendering chapter ( https://svgwg.org/svg2-draft/render.html) on what it means for an element to be or not be rendered with definitions for the terms "never directly rendered" and "not rendered". - Move the section on the display and visibility properties, currently in the Painting chapter ( https://svgwg.org/svg2-draft/painting.html#VisibilityControl), into the rendering chapter & integrate with the new section. - Link all prose references of "never directly rendered" and "not rendered" to the new section. - Create a new category of element (for use in the element definition blue boxes) "non-rendered element". I would hope that the element definitions in CSS Filters and CSS Masking could also be updated with these last two changes. ~Amelia
