I don't have time to review this completely now. I'll do it when I get
back home next week.
The specification text for flowed text is found at:
https://svgwg.org/svg2-draft/text.html
I will be revising this text over the next month in response to a very
useful discussion we had yesterday at the joint CSS/SVG meeting. I'll be
adding a property to dictate how text wrapping works when there are
holes in a shape as well as a method allow text to wrap into multiple
shapes.
