This tightly binds the list of element names in SVG to HTML, and also breaks assumptions inside SVG DOM that HTML5 may depend upon. Indeed SVG already has elements like <title>, <a> and <style>. <svg> <a><a> <title></title> <section></section> </svg> The <title> and <a> elements are SVGTitleElement and SVGAElement respectively and not HTMLElements. The section element is an SVGElement, not an HTMLElement. This isn't actually defined yet, but gives SVG authors some flexibility with unknown elements when embedded in HTML5. It would be really unfortunate if the SVG folks were prevented from using logical names like <content> or <section> because we parse them into HTML. > > Another solution could be SVG inventing their own elements for these > kinds of things.

SVG has a totally different font and styling model, different kinds of animations, filters, etc. The paragraph and span concept in SVG wouldn't be the same thing so it's not an antipattern. You would have to specify some kind of x/y coordinate and the width since SVG doesn't have a flow concept so there would be nothing to size or place against. Even if you could use HTML in the flow chart example it's not enough to use <p> since that wouldn't make the green <rect> any larger as SVG doesn't have a concept of nesting text inside a rect, and if you moved the <rect> to be a <div> now you have the problem of making sure the lines that come out of the box still connect with the sides of box. You'd also have problems like losing access to the <font>'s you defined in the SVG world in the embedded HTML world. Might be nice to add an <html> element with x/y width/height attributes to make <foreignObject> easier though! - E
