Maybe my issue is that I am trying to add the comment between elements?

<html>
         <head>
            <title>{$dash-cms-name}</title>{(:blah:)}
            <meta http-equiv="expires" content="Mon, 22 Jul 2020 11:12:01 GMT"/>


returns

[XPST0003] Expecting valid expression after curly brace.

The following query is a valid XQuery 3.1 expression:

  <x>{ (: bla :) }</x>

Do you use an older version of XQuery or BaseX? Are you looking for
something else_
