The issue I raised is that it is unclear how to include non-visual
foreign markup in SVG documents, in particular as the foreignObject
element seems to assume visual rendering. I think the draft either
needs to clearly define how to do that or explain why it does not;
so if there isn't a dedicated section in the draft that I missed
and you failed to point out, this is not satisfactory to me.

The <audio> element cannot be used to refer to non-visual foreign
markup, it can only be used to refer to complete external non-SVG
resources that are audible.
