Here we look at cljdoc features for APIs

Namespace docstrings **can** contain markdown.

And should support links repo [to articles](/doc/tests/md-features.md)
and inline repo images

![«test image 1 should appear»](/images/test-image-1.png)

Wikilinks work from namespace docstrings:
- a var local to this namespace [[exercise7]]
- a different namespace [[cljdoc-exerciser.ns2]]
- a var in a different namespace [[cljdoc-exerciser.ns2/whatever]]

Wikilink syntax [[that does not resolve to any var or ns]] is not converted to a link,
this includes any typos like [[cljdoc-exerciser.ns2/whatevs]] [[cljdoc-exorcisor.core]]

With wikilinks and root relative links, we discourage and don't need fully qualified links, but they should work:
1. [A fully qualified link to cljdoc-exerciser.core/excercise3](https://cljdoc.org/d/org.cljdoc/cljdoc-exerciser/CURRENT/api/cljdoc-exerciser.core#exercise3)
2. [A fully qualified link to cljdoc-exerciser.core](https://cljdoc.org/d/org.cljdoc/cljdoc-exerciser/CURRENT/api/cljdoc-exerciser.core)
