Comment 29 for bug 167335

It should be noted that flowRoot, etc are not in the SVG 1.2 spec anymore either - these were elements in a draft state of the document and the document was later refactored.

As a result - _NO_ software will be implementing support for flowRoot, etc in the future. Inkscape should fix this to use either <textArea> (flowed text) or break into individual <text> and <tspan>s
