+%description
+TyXML provides a set of convenient combinators that uses the OCaml type
+system to ensure the validity of the generated documents.  TyXML can be
+used with any representation of HTML and SVG: the textual one, provided
+directly by this package, or DOM trees (`js_of_ocaml-tyxml`), virtual DOM
+(`virtual-dom`) and reactive or replicated trees (`eliom`).  You can also
+create your own representation and use it to instantiate a new set of
+combinators.
