Re: New SVG-based renderMethod examples in VC Playground

Nice to see rendering getting more attention :)

Would you say that the concern of seeing exactly what the issuer intended can be met either by embedding the template or by embedding a hash-link to a template?

All of these examples use SVG templates that are stored in the VC itself, and are populated from digitally signed data from within the VC (everything is self-contained in the VC -- no external resources). This is a complementary approach to the one demonstrated last week as a part of the Open Attestation Render Method.

Granted, the digital wallet or verifier can choose to NOT use the issuer's rendering template and do their own thing, but the key benefit in this case is that not every digital wallet needs to re-create a visual look and feel for every credential type that is stored in their wallet (which might be in the hundreds to thousands of different types in a mature ecosystem). This is the promise of render methods; to provide an issuer-supplied unified look and feel for all VCs.

We learned a lot in the process and there's still quite a bit that we'd like to improve, but we thought it would be better to get this out to the community instead of waiting for it to be perfect before we released it.
