"Render Clojure data structures to a compiled representation of HTML. To turn
the representation into a string, use clojure.core/str. Strings inside the
macro are automatically HTML-escaped. To insert a string without it being
escaped, use the [[raw]] function.
A literal option map may be specified as the first argument. It accepts two
keys that control how the HTML is outputted:
`:mode`
: One of `:html`, `:xhtml`, `:xml` or `:sgml` (defaults to `:xhtml`).
Controls how tags are rendered.
`:escape-strings?`
: True if strings should be escaped (defaults to true)."
