Hello Paolo,

I’m not exactly sure what you mean by „inline-svg”. The discussion you linked 
to is about manually converting svg paths into lilypond paths. While this is 
possible it surely would get very complicated with more advanced svg.

But it should be quite easy to use the <image>-tag svg gives us by it’s 
specifications to embed any sort of jpeg, png or svg image.

It should technically be possible to take the contents of one svg file 
directly into another file, but I don’t think this would be very stable, as we 
then can easily get things like clashing ids and stuff. So that probably is 
not a particularly good option.

Note that when using <image> we can directly embed the image data in base64 
encoded form.
