<p>The practical consequence is that <code>bound(?_name)</code> cannot be used: it becomes <code>bound(\"some value\")</code>, which is not valid SPARQL. Guard a comparison with <code>coalesce</code> instead, which yields the fallback when the comparison cannot be evaluated:</p>
<p><code>filter(coalesce(?date &gt;= ?_startDate, false))</code></p>
<p>Multi-value placeholders behave differently: they are bound through their <code>values</code> block and are ordinary variables inside the query.</p>""";
