Liam,

Thanks for help,
Basex implements serialize function. This can do:
      
   let $params := <output:serialization-parameters xmlns:output="http://www.w3.org/2010/xslt-xquery-serialization">
                      <output:omit-xml-declaration value="yes"/>
                    </output:serialization-parameters>

    let $sf :=  fn:concat(fn:serialize(<h3>Features:</h3>,$params),
                        fn:serialize(<br/>,$params),
                        fn:serialize(
                            <ul>
                              <li>{$f1}</li>
                              <li>{$f2}</li>
                              <li>{$f3}</li>
                            </ul>,
                        $params))

Watch out that if $f1 (say) contains the string ]]> you'd be liable to a
cdata injection attack.

Having said that, no, I'd probably write an e() function,
declare function my:e($name as xs:string, $content as xs:string)
as xs:string
{
  return concat("<", $name, ">", $content, "</", $name, ">")
}

and use my:e("ul",
  concat(my:e("li", $f1),
         my:e("li", $f2),
         my:e("li", $f3))
and so on. Which gives you slightly more checking.

The implementation will probably generate &lt; and &gt; rather than
CDATA; XML says they're equivalent.

In XQuery 3 there's a per-element serialization option for CDATA
sections,
http://www.w3.org/TR/xslt-xquery-serialization-30/#XML_CDATA-SECTION-ELEMENTS
so if BaseX implements that you have a way to get closer to what you
want, perhaps, e.g. for generating RSS. However, you'd still need to
construct a string containing "<h1>" etc.
