I think this needs to be in a data URL.

I think base64-ing these should fall to the choice of the implementer and the data: URL spec should be references for if/when/how to do that or find a need/reason to. I'd rather not require it as it overly constrains the URL space (which won't makes us friends...) and base64-ing often bloats the size of plain text.

Heh...just realized this is the examples repo not the spec repo. I'll fix it here and fix https://github.com/digitalbazaar/vc-viewer to match. Thanks!

Still avoiding base64 in the example, but digitalbazaar/vc-viewer#13 does implement that as an option. |

Only comment is just me not knowing whether base64 encoding is a requirement here for proper parsing or not. Not a blocker because if we find out it needs it, we'll fix this, and if we don't, then we don't need the overhead.
