Testing links

There are many ways to add links to our documentation.
Let's see how these are translated when PDF is produced:

1. the most MD-like way, with text pointing to a URL, like look at the SPDX License List
2. spelling out the link after the text, like like at the SPDX License List https://spdx.org/licenses
3. even omitting the text, like look at https://spdx.org/licenses

Ideally we would use the first alternative, but we have to have a way for the actual URL to appear in the final (printed) text for ISO, I assume. If this is done automatically, that would be great.

Ah, there is also the case that we have internal links to other parts of the documentation.
How would these look like:

1. look at Annex A

I think in this case only alternative 1 makes sense, since you cannot have standalone relative links. In this case, the URL may be even omitted from the printed version.
