SVG without XML tag and why it should be put in to PRONOM with a PUID

[sobhanpiql]

I have some SVG files that has the signature 3C 73 at the start, there is no PUID for that signature, so it wont show any information and gives 0 on "Ids". At first I thought it was something wrong with my file, but the file is fine and I got many other files as this one. This SVG has basically been converted to JSX code format, but the SVG file and layout is still the same.

Here is an example of what a SVG file looks like when it is converted to JSX format:
