One of the major missing features in the SVG 1.1 full spec was the missing flow-text. To do flow-text one had to do word-wrapping and use tspans created by script. Implementing <textarea/> would improve the life of SVG content developers. Here is the spec section: http://www.w3.org/TR/SVGMobile12/text.html#TextInAnArea
So the only real question is if text wrapping can be implemented in terms of CSS layout. If it can, then we'll add this to the list of "pieces of SVG 1.2 which look sane enough to implement some day". If not, then we might not ever do this.
Eric, I am investigating with the SVG working group on the compatibility issue between the rules in SVG Tiny 1.2 and the CSS layout rules. I will report back.
Any update on this feature?
We will support a special version of <text> in SVG2 that allows to use wrapped text. It will follow CSS text layout.
