Example root target document

[clehner]

Examples include capability delegation documents and capability invocation documents:

• https://w3c-ccg.github.io/zcap-ld/#example-1 - first delegated capability / initial capability
• https://w3c-ccg.github.io/zcap-ld/#example-2 - invocation of first delegated capability
• https://w3c-ccg.github.io/zcap-ld/#example-3 - second-level delegated capability
• https://w3c-ccg.github.io/zcap-ld/#example-4 - invocation of second-level delegated capability

A third kind of document is mentioned in a few places, that is called the target or root document.

Should there be an example of a target/root document?
