How many levels of recursion does SVG support?

Question

I cannot get past 2 levels. (Tried on Iceweasel and Chromium.)

As a test, I tried a variant of the code presented in this earlier reply. This one consists of 3 sep

Answer 1

SVG when used as an image must be complete in a single file.

• a.svg is not an image
• b.svg is included as an image by a.svg and is therefore subject to the complete in a single file image rule so any images it contains must be included as data URIs.
• c.svg is ignored as b.svg cannot refer to external files.

Convert c.svg to a data URI and include it inline in b.svg to get round this.
