It would seem that the XQueryX stylesheet needs to generate more parenthesis
than it does currently.

Consider the following example:

<?xml version="1.0"?>
<xqx:module xmlns:xqx="http://www.w3.org/2005/XQueryX"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://www.w3.org/2005/XQueryX
                                http://www.w3.org/2005/XQueryX/xqueryx.xsd">
  <xqx:mainModule>
    <xqx:queryBody>
      <xqx:addOp>
        <xqx:firstOperand>
          <xqx:integerConstantExpr>
            <xqx:value>7</xqx:value>
          </xqx:integerConstantExpr>
        </xqx:firstOperand>
        <xqx:secondOperand>
          <xqx:flworExpr>
            <xqx:letClause>
              <xqx:letClauseItem>
                <xqx:typedVariableBinding>
                  <xqx:varName>c</xqx:varName>
                </xqx:typedVariableBinding>
                <xqx:letExpr>
                  <xqx:integerConstantExpr>
                    <xqx:value>5</xqx:value>
                  </xqx:integerConstantExpr>
                </xqx:letExpr>
              </xqx:letClauseItem>
            </xqx:letClause>
            <xqx:returnClause>
              <xqx:varRef>
                <xqx:name>c</xqx:name>
              </xqx:varRef>
            </xqx:returnClause>
          </xqx:flworExpr>
        </xqx:secondOperand>
      </xqx:addOp>
    </xqx:queryBody>
  </xqx:mainModule>
</xqx:module>

This generates the following XQuery, which does not parse:

(7+
 let $c:=5
 return $c
)


Parenthesizing the FLWOR expression would correct this.
